You mean something like this?


But, every time I think about this, it makes me wonder if this ins't 
what kerberos is supposed to do (aka I don't like having anything around 
which caches the clear-text passowrd).

If something like this were to occur, then it would be nice if it were 
standardised, so that all linux smb clients could use it. Including 
smbclient, smbmount, pam_mount (in case smbmount doesn't find a running 
daemon when pam_mount runs it), kio_smb, the gnome-vfs module for smb, 
komba2 (so it doesn't need your password to find shares on a server that 
doesn't allow guest connections) etc.

BTW, we got a patch from a user who had problems with smbmount's hanging 
when the smb server went down, to run umount2 on the mount point.
