mount.cifs on 13.04 fails with 13:Permission Denied when using -o guest

[Christopher Townsend]

Using the following command:
sudo mount -t cifs -o guest //server/volume /media/share
gets this error:
mount error(13): Permission denied
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

This command works flawlessly in 12.10.

Try adding sec=lanman to your mount options. This should probably be merged with https://bugs.launchpad.net/ubuntu/+source/cifs-utils/+bug/1113395

@SimonH,

That worked for me!

I'm going to dup this bug to the bug you mention.

Thanks!
