Question Samba and NTLMv2 Authentication

Hey guys, Iam trying to enable NTLMv2 encryption on samba ver 3.0.24. I know for a fact its very easy to setup because iam currently running NTLMv1 (older clients).. now that i have everything upgraded i want to do NTLMv2 fully.

It was setup like this, working great with ntlmv1:

/etc/samba/smb.conf :


encrypt passwords = yes
lanman auth = No
ntlm auth = Yes
client ntlm auth = Yes
client lanman auth = No
client plaintext auth = No

I then edited it to look like this:


encrypt passwords = yes
lanman auth = No
ntlm auth = No
client ntlmv2 auth = Yes
client ntlm auth = No
client lanman auth = No
client plaintext auth = No

... and yes i did change the local security policy on all windows XP machines to send NTLMv2 response only (reject LMAN and NTLMv1). But the clients dont seem to authenticate though the system.? is there a step iam missing?
