[Samba] Samba AD member server and cached credentials?

[Hansjörg Maurer]

Hi

we are using a recent samba server in an AD W2003 domain.
The AD DC's are located at the main location.
The samba member servers (file-servers) are  located at the
outside locations.

A User is able to logon to his Workstation, even if the
Domaincontroller is not available, if he has already logged on to
this workstation earlier (the clients caches the credentials).

But the client is anable to acces files on the samba server,
it the connection to the AD-DC at the main location is not available.

Is there a way that samba can cache credentials as a AD member server to,
in order to to allow the clients to access their files without 
connection to the
AD DC?

Thank you

Hansjörg
