Hi all,

I runned into a problem where I got  frozen mount points where a user had to 
authenticate.
After a few tcpdumps I found out that it looped the challenge / response 
messages every 2 sec.

I found out that the user was a member in about 400 groups.
We use AD so the KDC gave me a PAC in the ticket so the ticket became larger 
than 8k.
It seemed like the ticket was ignored by the fileserver and it asked for a new. 

I resolved this issue by setting the NO_AUTH_REQUIRED flag on the AD object 
holding the servicePrincipalName according to this page
http://support.microsoft.com/kb/832572/?


In hope that it will help someone else :-)
Best regards
