mount.cifs fails with user=domain/name in 14.04.1

[Thierry Guérin]

when mounting a Samba share, the user parameter is incorrectly parsed in 14.04.1 (this works in 12.04 and should work according to the man page):
mount.cifs //host/share /mnt/share -o user=domain/login,password=*** fails with error:
mount error(13): Permission denied

whereas
mount.cifs //host/share /mnt/share -o domain=domain,user=login,password=*** works as expected

Had this error after upgrading from 12.04, and had to use tshark to figure out the problem: the Session Setup AndX request contained 'domain/login' as Account, and nothing as the Primary Domain

Status changed to 'Confirmed' because the bug affects multiple users.

Happy there is a work around to this issue.

Can verify it start work again when adding domain=<workgroup/domain>

[Roberto Pensa (roberto16900)]

the work around does not work on 14.04 LTS!
There is no problem to mount from a samba share on 12.04 LTS but not vice versa!
This is typical for the so called stable releases. Hope it will be fixed very soon, but
don't believe that.

Did you try to specify "user=login@domain" in the options (instead "user=domain\\login" and "user=login,domain=domain")?
For me, that worked. :-)
