Probs with Auto-Populated Groups and LDAP

Hi,

i have a Problem with the Auto-Populated Groups.

No Users come inside !

Then i start the updater i received following message:

Search for auto-populated group members failed for group XXXX Server User.: Error looking up name on LDAP Server; See server log for further details.

The Ldap Task is running.The names is 8.5 desgin.

I dont know, but i cant send the Users in the Adressbooks from the Directory Asssistance about LDAP.

In Notes i can see all the Users.

maybe a cause?
