We have CAS Array with Exchange 2013 Servers CU 20 ( 3 CAS servers behind Windows NLB).
4 MAILBOX Servers in DAG.
We are not yet using MAPI and all the connection for Outlook Anywhere is going on RPC and authentication mechanism selected is NTLM.
Now I am being asked to change the Authentication mechanism to KERBEROS.
Can anyone help or suggest what I can do and what would be the challenges in doing this.
Thank you always for your great support.
