An authorization policy determines which permissions a user in CzechIdM has.
A policy is assigned to a role and everyone with this role gains the permissions determined by the policy as well.
The default role "User" gives implicit permissions, which all the users in CzechIdM have. This role is not assigned explicitly, it is simply default and is always applied (see the following chapter).
A new agenda of authorization policies = permissions for data and agendas has been tied to a role. Assigning permissions makes available both agendas on the front-end (or rather REST endpoints on the back-end) and permissions for data (make records in these agendas available) to the logged in user. Permissions for agendas (REST endpoints) are assessed according to the set permissions.
Real life example:
Let there be an agenda of identities. To be able to select from the identity dial (e.g. in filters) we need to be assigned a permission for an agenda of autocomplete for identities Identity - AUTOCOMPLETE
or Displaying in autocomplete, selections for instance with the evaluation type BasePermissionEvaluator
.
BasePermission
- a base permission; can be added in modules; basic permissions for the IdM core, which are identical for both permissions for access into agendas and for permissions for data:ADMIN
- administration - includes all operations ⇒ wildcard - there is no need to list all the operations (see IdmAuthorityHierarchy
)READONLYADMIN
- from IdM 13.0.14, universal read permission - includes all passive operations (AUTOCOMPLETE
, COUNT
, READ
), applicable for APP
group only, defining user that can view anything in IdM but cannot perform any change (read only administrator)COUNT
- number of records - The number of entities that match the filter. We do not have to have permissions for reading a agenda and details.AUTOCOMPLETE
- displaying of data in the autocomplete. We do not have to have permissions for reading a agenda but we need to select it somewhere from a menu (e.g. when requesting a role we can select it but if we had only this permission, we would not see the role in the role agenda). This permission enables reading a "trimmed" detail (we might limit this).READ
- a permission for reading the whole log - the log is displayed in the agenda.CREATE
- creating of new logs in the agendaUPDATE
- log updatingDELETE
- log deletingEXECUTE
- execute operations (start, cancel etc.)GroupPermission
- a group (target) permission (e.g. USER, ROLE …). A group of base permissions. This group is assigned specific domain classes (e.g. IdMRole) and determines which base persemissions it contains ⇒ what can be done with the given type.AuthorizationPolicy
- a policy according to which the permissions for a specific agenda (attribute groupPermission
) and specific domain type (attribute authorizableType
) are evaluated. It determines an evaluator (AuthorizationEvaluator) with specific settings (attribute ConfigurationMap
) and which base permissions (attribute basePermissions
) can be acquired if the evaluation passes.AuthorizationEvaluator
- authorization "evaluator" - it is basically an implementation of the individual types of the rule described above. Each evaluator carries information about which domain type and which setting it supports. Some can also be universal for more domain types (e.g. children ofBaseEntity
). In order to simplify the implementation of a rule, the class AbstractAuthorizationEvaluator
has been created, which can be simply inherited when adding another rule. The main evaluators will be described below. The main evaluator methods, which must be implemented (or overloaded from AbstractAuthorizationEvaluator
):getPermissions(policy, authorizable)
- returns a set of operations (the set BasePermission
), which the currently logged in identity can perform with a given domain object according to the given policy (e.g. READ, UPDATE)getPredicate(…)
- returns a jpa criteria predicate, which can be "stuck" onto a where clause ⇒ the query then returns a result which can be paged and ordered. The result contains data, which we have permissions for according to the given policy. It is recommended to write the predicates as subqueries with exists
, to prevent problems with joining tables (if, of course, it is not something simple).supports(authorizableType)
- which doamin type is supported by the evaluatorsupportsPermissions()
- returns true if the assigned permissions are supported. False - it defines them itself internally (e.g. AbstractTransitiveEvaluator
).getAuthorities(policy)
- returns a set of operations (the setBasePermission
), which the currently logged in identity could perform according to the given policy (e.g. READ, UPDATE).AuthorizableService
- an interface for labeling a service working with entities that it supports evaluating of policies for permissions for data. This has been added mainly because of backward compatibility - permissions for data are linked to individual agendas one by one. The policies can thus be configured only for domain types with services supporting this interface.AuthorizationManager
- loads and evaluates the set policies for the logged in identity throughout the application:AuthorizableService.findSecured(…)
)controllers
.AuthorizationEvaluator
implementation class ⇒ when evaluator implementation is renamed or moved into different package, then authorization policy with modified evaluator has to be reconfigured too (or change script has to be provided).
getPermissions
or getPredicate
evaluator's method, don't forget to check identity is logged in securityService.isAuthenticated()
, if evaluator cannot be used in public endpoints.
getPredicate
evaluator's method, don't forget to check policy has evaluated permission assigned hasPermission(policy, permission)
.
For some entities was added additional base permissions, which extends BasePermission
above.
PASSWORDCHANGE

Cache is used for evaluating authorization policies and permissions by AuthorizationManager
:
core:authorization-policy-cache
- Cache stores active authorization policies of currently logged user. Cache is evicted after user log out. When authorization policies configuration is changed, then user is logged out and cache is evicted (after permissions removal only). Cache expiration is 2 hour, e.g. if user forgot to log out.core:permission-cache
- Cache stores permissions (for data) of currently logged user. Cache is evicted after user log out. Cache expiration is 1 minute - if data structure is changed, then permissions are actualized after this duration. When authorization policies configuration is changed, cache is evicted (completely).
Adds the default implementation of the AuthorizationEvaluator
methods. It is used as a parent for the other evaluators.
Serves as a parent for evaluating permissions according to the derived objects - for example, I have a permission for the assigned role if I have a permission for the identity, etc. See the children of this abstract class below (IdentityContractByIdentityEvaluator
).
include-permissions
) - Only selected permissions can be used from owner permissions transitively. Configuration property has to be used in evaluator configuration properties (in evaluator form attributes) and getPredicate method
has to check evaluated permission is selected (see IdentityContractByIdentityEvaluator
for example).
Serves for assigning the configured permission for the configured domain type - for all the data of the given type. It can be used when we want to give an access to an agenda including the access to all data. It is used, for example, for an admin with the configuration - any type (permissions for all the Identifiable
children) + BasePermission.ADMIN
. It can also be used for assigning the base permission for displaying data during autocomplete (see BasePermission.AUTOCOMPLETE
above).
BasePermissionEvaluator
is also used for simple sharing of an agenda which does not support permissions for data yet. Agendas which do not support permissions for data yet are not linked to the domain object, which can be see on the front-end as well. No other evaluator can be selected for these agendas
"Shares" the object with the given uuid. It is suitable when we are not able to configure another, more general rule - simply put - when somebody needs to see only one log from the whole agenda, it can be "shared" via the identifier (it would be nice not to enter the uuid directly in the configuration but to use autocomplete … coming soon).
"Shares" the object with the given identifier so that it is possible to enter uuid of the code of the given entity. For this evaluator, it is necessary to choose the entity type for which it is intended - does not work across entities.
Gives currently logged user a permission to work with his own identity.
@since 10.3.0
A permission for identities by user type.
form-projection
) - Add permission to selected user type or to default type (user without type is specified).A permission for contracts which are my subordinates. Overloadable filters are used for evaluating subordinates or managers.
@since 10.3.0
A permission for identities which are my subordinate contracts. Overloadable filters are used for evaluating subordinate contracts or contract managers.
Gives a permission for industrial relations according to the permission for identity ⇒ e.g. if I have a permission to read an identity, I have a permission to read its IR. AbstractTransitiveEvaluator
is used here.
include-permissions
) - Only selected permissions can be used from identity permissions transitively.IdentityByContractEvaluator
- configure one of them.
@since 10.3.0
Gives a permission for identity according to the permission for identity contract ⇒ e.g. if I have a permission to read an contract, I have a permission to read its identity.
IdentityContractByIdentityEvaluator
- configure one of them.
Gives a permission for guarantees of a industrial relation (setting a guarantee "directly") according to the permission for a industrial relation ⇒ e.g. If I have a permission to read IR, I have a permission to read its guarantees. AbstractTransitiveEvaluator
is used here. If I have a permission to edit IR, I have a permission to edit (add or delete) its assigned guarantees.
Gives a permission for assigned roles according to the permission for the identity ⇒ e.g. If I have a permission to read an identity, I have a permission to read its assigned roles. AbstractTransitiveEvaluator
is used here. If I have a permission to edit the identity, I have a permission to edit (add or delete) its assigned roles.
@since 10.3.0
Gives a permission for assigned roles according to the permission for the contract ⇒ e.g. If I have a permission to read an contract, I have a permission to read its assigned roles. AbstractTransitiveEvaluator
is used here. If I have a permission to edit the contract, I have a permission to edit (add or delete) its assigned roles. Logged identity can see / edit roles assigned to managed contracts only.
@since 9.7.12
Gives a permission for assigned roles according to the permission for the role definition ⇒ e.g. If I have a permission to read an role, I have a permission to read its assigned roles. AbstractTransitiveEvaluator
is used here. If I have a permission to edit the role, I have a permission to edit its assigned roles. It's usable mainly with can be requested permission - enables copying assigned roles from other identity.
can-be-requested-only
) - Add permission for role requests only (can be requested). Usable, when assigned roles need to be copied from another user. Other permissions will not be added.<note tip>If you want to enable copying all assigned roles (the same behavior < @9.7.12), then configure BasePermissionEvaluator
with Can be requested
permission to all assigned roles (``IdmIdentityRole``).</note>Gives a permission to work with roles which I guarantee. Role guarantee can be configured by:
This evaluator solves both ways (or).
Evaluator can be used for UC, when role guarantee can assign his roles to users (@since 11.1.0). The authorization policies have to be set as follows:
Gives a permission for authorization policies according to the permission for a role ⇒ e.g. if I have a permission to read a role, I have permission the authorization policies assigned to it. If I have a permission to edit a role, I have a permission to edit (add or delete) authorization policies assigned to it.
Gives a permission for automatic roles according to the permission for a role ⇒ e.g. if I have a permission to read a role, I have a permission to read the automatic roles assigned to it. if I have a permission to edit a role, I have a permission to edit (add or delete) the automatic roles assigned to it.
Gives a permission for application configuration (read, set…). If we want to get permissions for the secured configuration items, we need to set the parameter secured
to true
.
Assigns permissions for a role according to the role attribute "canBeRequested". This means that if I have a role with this evaluator, I will get permissions only for those roles the attribute of which "canBeRequested" is set to true.
Gives a permission for accounts in system according to the permission for the role ⇒ e.g. If I have a permission to read a role, I have a permission to read its accounts in system. AbstractTransitiveEvaluator
is used here.
Gives a permission for accounts in system according to the permission for the role catalogue ⇒ e.g. If I have a permission to read a role catalogue, I have a permission to read its accounts in system. AbstractTransitiveEvaluator
is used here.
Gives currently logged user a permission to work with his own role requests. This functionality can be configured another way - by combination RoleRequestByIdentityEvaluator
and SelfIdentityEvaluator
with adding permission CHANGEPERMISSION
. CHANGEPERMISSION
on identity gives permissions READ
, CREATE
, UPDATE
, DELETE
to identity's role requests automatically.
Gives a permission for role requests according to the permission for the identity ⇒ e.g. If I have a permission to read a identity, I have a permission to read its role requests. CHANGEPERMISSION
on identity is wildcard here - it gives permissions READ
, CREATE
, UPDATE
, DELETE
to identity's role requests. AbstractTransitiveEvaluator
is used here.
Gives a permission to work with role requests which I has to approve. All involved identities (approver, applicant, implementer …) will have this permission. This policy is needed for workflow approval, where approver doesn't have a permission to read applicant. Approver will be applicant's manager (guarantee) in more cases, but even some "stranger" can have approval task assigned.
Gives a permission for accounts in tree node according to the permission for the role ⇒ e.g. If I have a permission to read a role, I have a permission to read its accounts in tree node. AbstractTransitiveEvaluator
is used here.
Gives a permission for form attributes according to the permission for the form definition ⇒ e.g. If I have a permission to read a form definition, I have a permission to read its attributes. AbstractTransitiveEvaluator
is used here.
@since 9.4.0
Gives a permission for form attributes according to the permission for the code list ⇒ e.g. If I have a permission to read a code list, I have a permission to read its attributes.
@since 9.4.0
Gives a permission for code list items according to the permission for the code list ⇒ e.g. If I have a permission to read a code list, I have a permission to read its items.
@since 10.3.0
Gives a permission for code list items according to the permission for the code list and item codes.
codelist
) - Items from selected code list.item-codes
) - Add permission to code list items by their codes. All items from selected code list will be used as default (use comma as separator - more item codes are supported).For show requests only for assigned implementers. With this evaluator can user show and edit only requests where is implementer (directly or from roles).
For show accounts only for identities witch have relation (via identity-account entity) on the accounts. With this evaluator can user show accounts where is owner.
For show identity-accounts only for identities witch have permissions on the accounts. With this evaluator can user show and edit only identity-accounts where is owner for the accounts.
@since 12.2.0 Gives currently logged identity permission to work with a specified report. The report is specified by executor name (e. g., 'identity-report'). Only one report can be used; if you need to give access to multiple reports, create the permission multiple times. This evaluator limits which report executors are returned as available by ReportManager. For generated reports, the user is able to see EVERY report of the type which was created. To download a report, a simple READ permission is not enough, a CREATE or ADMIN permission is needed.
Gives currently logged identity a permission to work with his own reports ⇒ logged identity is report creator.
@since 8.2.0
Permissions to identity form attribute values. By definition (main if not specified) and attrinute codes (all if not specified).
Evaluating authorization policies for identity extended form attributes has to be enabled by configuration. Configure permissions for form definitions together with this evaluator - FORMDEFINITION_AUTOCOMPLETE

The configuration of default permissions for agendas and data for all logged in users is carried out through the default role according to the application configuration. The default role can have, similarly to other roles, configured permissions for agendas and data. After logging in, these permissions will be filled in the context of the logged-in user (authorities and authorization policies) - the role itself does not figure in the assigned roles of the user. The default role can be used mainly for adding base permissions for the autocomplete (of roles, identities) and the like.
This is a typical setting for the userRole - regular user as defined in the installation package.
If we want to read an identity profile including its assigned roles and IR, to enable password change and to request roles, it is possible to set the default role authorization policies as follows:
UPDATE
. But exits own permissions for each operation (MANUALLYDISABLE
or MANUALLYENABLE
)
CANBEREQUESTED
permission for copying roles into request by other identity.
If you want to enable the managers of the users to read their subordinates and change their permissions on managed contracts only:
With this setting manager will see even other contracts, which not manages (⇒ all identity contracts) and can assign role to other contract. This is the reason, why new authorization policies and setting was introduced in version 10.3.0. </note>
Default settings of permissions for delegations are defined in the role 'Delegation (delegationRole)'.
The Helpdesk role as defined in the installation package should have following additional permissions:
The virtual system implementer (~approver) role should have following additional permissions:
If we want to read and edit roles where we are a guarantee, including the assigned permissions, automatic roles and accounts on target system, the authorization policies can be set as follows:
If wee want to configure application code list, the authorization policies can be set as follows:
If we want to enable for currently logged identity change all basic identity attributes (e.g. login, first name, surname), the authorization policies can be set as follows:
If we want to enable for currently logged identity read / update for some form attributes (e.g phone
) from some form definition (e.g. from main definition) on identity detail (tab more information), the authorization policies can be set as follows:
phone
attribute: Forms - values (IdmIdentityFormValue) | Read, Update | IdentityFormValueEvaluator - select form definition same as above, enter phone
as attributes
If we want to enable for currently logged identity read / update for some contract form attributes (e.g. other manager
) from some form definition (e.g. from main definition) on contract detail (tab more information), the authorization policies have to be be set as follows:
other manager
attribute: Forms - values (IdmIdentityContractFormValue) | Read, Update | IdentityContractFormValueEvaluator - select form definition same as above and enter other manager
as attributes.Assignment of roles is normally approved by the standard approval process. The approval process may be skipped by executing the bulk action for Role assignment with unchecked Approve, but only if the user has the following permission:
To employ permissions for data for a new domain type it is necessary:
AuthorizableService
for the service working with entities - is needed to use correct GroupPermission
and entity type - don't reuse groups and entity types from different agendas. This requires the repository not to search for log via hql queries but via jpa criteria api (this is the main adjustment for the existing services where all the filters need to be rewritten). An example can be found in DefaultIdmAuthorizationPolicyService
.AbstractAuthorizationEvaluator
has been created, which can be simply inherited when adding another rule. Example:/** * Adds permission for creating a new role only * */ @Component @Description("Adds permission for create new role") public class RoleWriteNewOnlyEvaluator extends AbstractAuthorizationEvaluator<IdmRole> { @Override public Set<String> getPermissions(AuthorizationPolicy policy, IdmRole entity) { Set<String> permissions = super.getPermissions(policy, entity); permissions.add(IdmBasePermission.CREATE.getName()); return permissions; } }
AuthenticationManager
, which finds all implementations of the rules according to the application context, offers supported types and so on.
