Set HKLM\Software\Novell\ZCM\AgentSettings\DoNotFetchUserGroups = True
This key does not prevent the use of groups with ZENworks; the registry key name is not a clear indication of its function. This key disables a very specific feature of the DLU policy package that is not used by majority of the customers who use DLU policy packages. In the Login Restrictions portion of a DLU package, you can explicitly exclude users from the DLU package who were assigned the policy package. This exclusion can be made for individuals or groups. Support for groups in the exclusion portion of the DLU package causes a user's group memberships to be read a second time, even if the policy package does not use this feature.
Enabling this key on the workstation will disable support for groups, for this single feature, and eliminate a group membership request. Group membership requests take slightly longer than other requests due to the time required to search for Dynamic eDirectory Groups and verify membership in those groups if located. This delay can occur even if Dynamic eDirectory Groups do not exist, because the search to locate any that might exist must still occur.
