Authentication NTLM client and server side

Hi,

during NTLM authentication, server doesn't receive user password. so if you enable NTLM authentication on client side, F5 doesn't know user password to use it for server side authentication. it is not a F5 APM limitation but a NTLM proxy limitation. Microsoft TMG had the same limitation.

when working with NTLM client side authentication, a password-less authentication must be used on server side. the one used in such deployment is Kerberos Contrained delegation (Kerberos SSO)
