Check Configuration for the "PWM Admin Query String". This setting determines which users have access to the PWM admin functions. E.g.:
(groupMembership=cn=pwmadmins,ou=groups,dc=example,dc=com)
In this case there is a group "pwmadmins", and the user must be a member (i.e. have the attribute groupMembership set) of this group.
Another option would be:
(|(cn=YourUserID)(cn=YourColleagesUserID))
This would allow you and your colleague.
Hope this helps! By the way, there are more such settings like the proxy user and a user/group that has/have permissions to create guest users.
