samba-users: Re: [Samba] Still can't mount Samba shares from oth

Re: [Samba] Still can't mount Samba shares from other Samba server - some slight progress

From: Mike Leone <turgon_at_nospam>
Date: Fri May 14 2010 - 03:35:27 GMT
To: Samba <samba@lists.samba.org>, Philadelphia Linux User's Group Discussion List <plug@lists.phillylinux.org>

On a hunch, I removed the

winbind separator = +

And can mount shares from the command line:

# mount -t cifs //workhorse/OldHome /OldHome -o
user=DACRIB\\turgon,password=******** --verbose

mount.cifs kernel mount options:
unc=//workhorse\OldHome,domain=DACRIB,ver=1,rw,user=turgon,,,,,,,,ip=10.0.0.20,pass=********

Note that I had to escape the backslash separator, both in the
DOMAIN\USER entry, and (in this case) also in the password, which has a
exclamation mark (!) in it.

root@Dual-Booter:/etc# ls -la /OldHome/
root@Dual-Booter:/etc# ls -la /OldHome/
total 4
drwxr-xr-x 13 DACRIB\turgon DACRIB\domain users 0 2010-05-09 18:25 .
drwxr-xr-x 29 root root 4096 2010-05-12 23:03 ..
drwxrwxrwx 11 DACRIB\turgon DACRIB\domain users 0 2010-05-09 18:25 mjl
drwxrwxrwx 23 DACRIB\turgon DACRIB\domain users 0 2010-03-27 14:30 turgon

So YAY! for that. Still can't mount it in fstab, however. It doesn't
work if I specify the username and password in the entry, nor does it
work if I put it in a credentials file. No indications that I can see as
to why it's failing.

Is using samba really supposed to be this hard? :-(
