what is relation of Active directory and Kerberos with java?

Hi

Thank you for reading my post

Can some one please explain what is relation of Kerberos and Active Directory with java?

By my knwledge LDAP (such as AD) can store many information and also userID/password which we usually use for authentication.

What is relation of kerberos with LDAP (AD) and whether kerberos provides authentication facilities?

for example, does unix systems use kerberos for authentication purpose?

Thanks

AFAIK, Kerberos is the communication protocol for authentication in AD, the other supported protocol is NTLM, for compatibility with pre-Win2k systems.Read this: http://technet2.microsoft.com/windowsserver/en/technologies/featured/kerberos/default.mspx
