Create evaluator with restrictions on one entity

authorization, certificate, codeable, evaluator, evaluators, restrict, restrictions

Codeable evaluator is useful for restricting privileges on selected entity. For example, if you want one user to be able to see only other user (with defined username or uuid), or for restricting that user to see only a role (defined by code or uuid).

This tutorial describes how admin can create a new evaluator to achieve that.

Define evaluator with restriction for one identity (user)

This section describes how to create evaluator that restricts permission to see only one identity (user).

Step 1. - Get username of user

In first step we must get username of identity that will be restricted by this new evaluator.

Step 2. - Create codeable evaluator for role

For this step a role must exist so we can hook a new evaluator to this role. If you don't have such a role, please create one. Once you have a role, go to its submenu Permission and then add new evaluator by button Add.

Step 3. - Define new evaluator

On a modal window, select:

Entity type: IdmIdentity.
Evaluator type: CodeableEvaluator

Then, application will display an evaluator configuration dialog with one option marked identifier. Put UUID or username of an user (identiti) into this field.

Save the new evaluator. If the action was successful, you can verify new evaluator in the list of active evaluators.

Step 4. - Add role to user

Choose some other user (the user you want to give the permission to) and add him the role you configured. This user now obtains a new permission as defined in the evaluator.

Step 5. - Result

Final result. We assigned a role to the richard.roe. This user now can see the john.doe identity in IdM.

Define evaluator with restriction for access to one certification authority

This tutorial is similar to the first one. Instead of an identity, we grant user a permission to work with some certificate authority. For example, this restriction can be used for adding permissions to request certificates only from particular certificate authority authority. If you have multiple CAs defined, you can create one role for each of your CAs an then assign those roles to users as necessary.

Step 1. - Get code of certification authority

Get the code of certification authority.

Code can be used in 1.3.0 (and later) version of crt module. If you use lower version of crt module, you have to use UUID as an identifier. UUID can be found in browser URL when you open the certificate authority detail page.

Step 2. - Create codeable evaluator for role

For this step you have to have a role created (if you do not have such a role, create it). We will now hook an evaluator to the role. For this, go to role's submenu Permission and then add new evaluator by clicking the Add button.
