 ==== Preparing Active Directory ==== ==== Preparing Active Directory ====
 +You must prepare your Active Directory for the CzechIdM integration, mainly:
 +  * Enable LDAPS (SSL-protected LDAP protocol) on the AD. This is vital for production deployments. Also, CzechIdM will not manage users' passwords if not connected to AD through LDAPS.
 +  * Create an user account for the CzechIdM. Identity manager will use this account to perform operations on your AD. Although you can use a Domain Administrator account, we highly discourage it.
 +    * This is simply a Domain User account like any other, but you should create it in different subtree than you want to manage through IdM.
 +  * Grant the CzechIdM user permissions on your AD.
  
 +=== Granting permissions ===
 +Suppose we have a domain ''PISKOVISTE.BCV'' with corresponding domain components ''DC=piskoviste,DC=bcv'' and the IdM application user is ''CzechIdM (czechidm@piskoviste.bcv)''.
 +
 +  * CzechIdM needs to ''read'' AD configuration and schema subtrees. In our case:
 +    * ''CN=Configuration,DC=piskoviste,DC=bcv''
 +    * ''CN=Schema,CN=Configuration,DC=piskoviste,DC=bcv''
 +
 +Ability to read schema and sufficient AD configuration should be there by default for an authenticated user. Probably no need to adjust it.
 +
 +  * CzechIdM needs ''full control'' on subtrees which it will manage. Suppose we need to manage users, groups and computers and that we have a fairly simple setup. We grant full control to those subtrees:
 +    * ''CN=Computers,DC=piskoviste,DC=bcv''
 +    * ''CN=Users,DC=piskoviste,DC=bcv''
 +    * ''OU=Groups,DC=piskoviste,DC=bcv''
 +
 +Which subtrees you need to grant privileges on depends on the actual directory tree of your Active Directory.
 +
 +**Granting full control to CzechIdM application user**
 +
 +The process is fairly straightforward. Just repeat it for every root of every subtree you need to grant the rights on.
 +
 +  - Open the ''Active Directory Users and Computers''.
 +  - Right-click a container (in our case it was simply marked ''Users'').
 +  - Choose ''Delegate Control''.
 +  - Choose the ''CzechIdM (czechidm@piskoviste.bcv)'' user.
 +  - Choose ''Create a custom task to delegate''.
 +  - Choose ''This folder, existing objects in this folder, and creation of new objects in this folder''.
 +  - Tick the ''Full Control'' checkbox. This will tick all possible checkboxes in the dialog window.
 +  - Check the summary and finish the wizard. Changes are effective immediatelly.
 +  - Repeat for other subtrees as necessary.
 +
 +<note important>
 +**CzechIdM has to have access to objects directly referenced from objects you manage.**
 +
 +For example:
 +
 +A user is member of some groups, this is noted in his ''member'' attribute. If you want to manage the ''member'' attribute, the CzechIdM also has to have full access to the subtree with user groups.
 +However this requirement is not transitive in groups hierarchy.
 +In AD, you have a ''Groups\Domain Users'' group and every domain user is a member of this group. This means that every domain user has a ''member'' attribute which contains the ''Groups\Domain Users'' group DN.
 +But the ''Groups\Domain Users'' is itself a member of ''Builtin\Users'' group.
 +
 +If you want to manage your users and their group membership, you therefore need to grant full control on ''Users'' (to manage users) and ''Groups'' (because this is where ''Domain Users'' group is) **even if you do not want to manage groups themselves**. This is because of consistency checks performed by CzechIdM upon account provisioning.
 +
 +But you **do not need** to grant anything on ''Builtin'' because this is referenced from an user account only indirectly.
