[Samba] panic in pwnam_r after a reconnect

[Dragan Krnic]

Is there some explanation for the panic in pwnam_r when a session
reconnects after a while?
This is an exagerated example. The user leaves on a Thursday,
comes back next Tuesday - bang!

My Samba 3.0.24 runs under a SuSE 10.1.
The passwd files are used for authentication.
