The thing is my share point development team want to have Kerberos authentication to be enabled in domain as its get more security advantages for the apps.. When I see the Domain Controller GPO "Netwrok Security:LAN Manager authentication level" not defined.. What need to be done inorder to enable Kerberos?
Cliff GaliherCommented:
2008 R2 uses Kerberos v5 by default out of the box. Developers just need to code accordingly.
Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

How do I check my AD using Kerberos authentication?.
Tony MassaCommented:
You can use wireshark to "watch" the authentication or just check the security logs of any domain controller. The log entries will indicate which authentication protocol is being used for users and computers. Look for event IDs of 4624 on 2008 and higher DCs.  They will have the "authentication package" that was used.  On 2003 DCs, look for event id 540.

Kerberos has been the default protocol for many years now, and falls back to NTLM only if kerberos fails.  

SharePoint needs to be set up properly for kerberos,  the domain controllers already support it.
