Successfully added the OpenMediaAgent to Active Directory using Kerberos and Samba. Able to see the users using wbinfo and getent.
But the WebGUI Users option throws "Communiation Failure" and the Group option works fine. There are around 3000+ AD Users and 100+Groups. UIDs & GIDs matches between /etc/login.defs, /etc/samba/smb.conf with the list from "getent passwd".
Unable to proceed as not other detailed error messages seen. Appreciate any help.
