[Samba] Cyclic authentications from user already logged on.

[teneagles]

This problem is being experienced on a RedHat Enterprise 4 server, with
Samba version 3.0.11. The user seems to be repeatedly authenticating
every few seconds, even though they have been authenticated once, are
logged onto the domain, and using various shares. 

Only one of the 30 users on the network has this issue.

Any ideas would be appreciated.
