Description:
Dynamic Groups policy failed to look up an object in directory. Possibly the object was deprovisioned, moved, renamed or deleted.
Dynamic Groups policy has received a notification about certain changes to the object, but cannot find that object by Distinguished Name (DN). This issue may stop Active Roles from updating the members list of the Dynamic Group. Dynamic Groups policy will attempt to look up the object upon a subsequent notification about any changes to that object. If this issue persists, review the membership rules of the Dynamic Group to correct or remove invalid rules. You can do this using the Membership Rules tab in the Properties dialog box for the Dynamic Group in the Active Roles console.
