LDAP users missing when working with memberOf


I am trying to set up Seafile (Community) with LDAP pointing to Active Directory. Everything works fine including authentication. After applying filter with memberOf attribute, some members of this group are missing.

I was checking mail attribute and memberof attribute of missing users, everything fine here. Why those users are not shown? Any ideas?

Running in Ubuntu Server 16.04 + seafile server 6.2.5


Have they already logged in?

I think each user must login once in ce until it is visible.


I was trying to set the filter to another group. It shows users never login before, but here is the same problem, some user in the group are missing and not shown in user list.


Can somebody help here?
