Re: [PLUG] wbinfo -a fails plaintext auth; passes challenge/response

Any clues?

I also can't mount shares, I'm guessing it's all related:

$ sudo mount -t smbfs -o username=turgon,password=*******
//workhorse/OldHome /mnt
mount error(13): Permission denied
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

The "turgon" account is a Domain Admin, not to mention owner of the
share I am trying to mount.
