Hi Piotr,

Are you pertaining to the identity.identity table, if so you may want to do a sync.
You may check the below link for the details

once done, Wait 20-30 minutes to allow the Sync to complete. You may check the sync status from the table lsyncengine].erunhistory]
 
if the "Runstatus" is "1" it means it's synchronizing but if its "2" it means its completed

Then you may check the identity.identity table if the values are updated

Hope this helps

Hi,

I’ve another problem. Every AD group has MembersResolved attribute set to 0 and users can’t open tasks destinated to the AD groups.

What could be the reason?

Kind regards,

Piotr
