First of all install the package univention-custom-ldap-acls via the command

univention-install univention-custom-ldap-acls

The package should be create some new UCR variables. Check these with the following command

ucr search acls

You should see these variables:

ldap/acls/custom/univentionCustomACLReferenceGroupModify/attrs: uniqueMember,memberUid
ldap/acls/custom/univentionCustomACLReferenceGroupModify/create: yes
ldap/acls/custom/univentionCustomACLReferenceGroupModify/description: Bearbeiten von Gruppen
ldap/acls/custom/univentionCustomACLReferenceGroupModify/filter: objectClass=univentionGroup
ldap/acls/custom/univentionCustomACLReferenceUserCreate/create: yes
ldap/acls/custom/univentionCustomACLReferenceUserCreate/description: Anlegen von Benutzern
ldap/acls/custom/univentionCustomACLReferenceUserCreate/filter: objectClass=posixAccount

Create extended attributes

After that, switch to the Univention Management Console and open the LDAP directory module. Expand the tab univention and search for custom attributes -> LDAP ACLs Click on "Add" and choose Settings: Extended attribute. Fill out the text fields as the follows: Tab General:

Unique name: edit-user
Short description: Editing users

Tab Module:

Modules to be extended: Container: Container, Container: Organizational Unit 

Tab LDAP mapping:

LDAP object class: univentionCustomACLReferences
LDAP attribute: univentionCustomACLReferenceUserCreate
Tick remove object class if the attribute is removed

Tab UMC:

Ordering number: 1
Tab name: authorization

Tab Data type:

Syntax class: uerDn
Tick multi value
Tick editable after creation

Editing container

The next step is, to modify the users container in the LDAP directory module. Edit the container via right click -> Edit and move to the tab authorization. Now you can add one or more userDNs to assigning authorizations to that users, e.g execute the following command in the command line (replace <username>):

univention-ldapsearch uid=<username> | grep ^dn 

The output should be something as the follows:

dn: uid=<username>,cn=users,dc=example,dc=com

Copy the output, except the dn:, into the text field and click on save.

Create policies for users

The next step is, to give the user the permission to use the users module after the log in. Go to the users module and open the user, that you placed in the authorization field. Move to the tab Policies and open Policy: UMC. Create a new policy and name it "edit-user". Choose "UDM - Users (udm-users)" as an allowed UMC operation and save the settings after that.

Now the user is qualified to edit users via the UMC.
