The fix did the trick.
Thank you very much!

Hi,

I have installed i-doit pro trial version and currently having some issues with person groups mappings.

LDAP is configured and working fine. Users are found in the AD and successfully authenticated.
I have also created a new person group and configured LDAP-Group mapping.
This also works fine, users are on their first login assigned to this group.

The problem is that every user is also assigned to the Admin group.
So every user is a member of this group with LDAP mapping and the Admin group.

I can't seem to find where to disable automatic assignment to Admin group.

There is a file "isys_application.class.php" with the following line :

define("CLDAPGROUP_IDS", isys_tenantsettings::get('ldap.default-group', ''));

Editing the line to something like

define("CLDAPGROUP_IDS", isys_tenantsettings::get('ldap.default-group', '10'));

did not change anything.
User are still assigned to the Admin group and LDAP mapped group.

Is there a way to disable this automatic assignment of all users to Admin (object ID 14) group?
