[Samba] Cannot mount with newer samba

[Flemming Bjerke]

At my nt-server, the c-drive was overfilled. After that I could not mount it 
from redhat7.3 samba 2.2.3. The following was said.

tdb((null)): tdb_open_ex: could not open file 
/var/cache/samba/unexpected.tdb: No such file or directory
1541: Connection to <servername> failed
SMB connection failed

I tried opgrading to samba 2.2.5, and I have also opgraded to redhat8.0. Now 
it just tell me:
1541: Connection to <servername> failed
SMB connection failed

I have an old mandrak8.0 at another partition, and it mounts the nt-server 
perfectly.

I use exactly the same fstab line in both cases. The corresponding mount 
command does not mount in the redhat cases.

mount -t smbfs //server/shared /mnt/g-drive -o   
                            user=<user>,password=<pswd>,uid=500,user,auto

Is this a bug in the newer samba versions?
