Hi, If I change the base DN to sync in cache refresh, I notice one times its adding but then in next trigger it fails. 2020-10-11 11:40:48,846 INFO [Thread-387] [gluu.oxtrust.ldap.cache.service.CacheRefreshTimer] (CacheRefreshTimer.java:493) -

Ok, I think there are basic formula you need to understand on Cache refresh. - Cache Refresh _pull_ user's information from LDAP/AD backend. You already know that. LDAP/AD backend is _not_ Gluu Server's LDAP but some other organizational data source from where you are _pulling_ your user's information. - Your _backend_ LDAP or AD _might have_ duplicate entries because this type of practice wasn't enforced in old time. - When you run Cache Refresh, scenario will happen: - If you have two users with same UID ( i.e. "kamlesh" ), Gluu Server will _pull_ one user into Gluu's LDAP ( i.e. Couchbase or Gluu-OpenDJ ). Another user will be eliminiated and you will see the info that... "1 user can't import because duplicate entries". Duplicate entry does't mean... Gluu's datasource ( i.e. Couchbase or Gluu-OpenDJ ) has _two_ entries BUT your backend _tried_ to push two users with same UID. That's uniqueness. That's the basis of uniqueness.

Hi, No, Im trying to test GLUU and setup a POC. Its my current test environment and has unique UIDs. There are no duplicate entries.

Hi team, After removing the content of problem file "problem-inum-list.txt" cache refresh works for basic attributes cn, sn, uid. However, userpassword is not synched. Please can you share a sample script to sync userpassword, groups and groupmembership.

Closing this one. There is [another](https://support.gluu.org/cache-refresh/8963/cache-refresh-for-new-attributes/) ticket.
