[Pkg-samba-maint] Bug#572691: samba shares can no longer be mounted by user

Package: cifs-utils
Version: 2:4.1-1
Severity: normal

Read the instruction in NEWS, added a line to /etc/fstab.

moria:/home/tobi# ls -la /sbin/mount.cifs 
-rwxr-xr-x 1 root root 27716 Mar 24 08:06 /sbin/mount.cifs

moria:/home/tobi# cat /etc/fstab  # (remark: only last line given)
	//smbserver/share    /mnt/smb_share smbfs user,noexec,noauto   0       0

but (as normal user):
- not-having mount.cifs setuid:
	tobi at moria:mount /mnt/smb_share
	/sbin/mount.cifs: not installed setuid - "user" CIFS mounts not supported.	
- when having setuid:
        tobi at moria:mount /mnt/smb_share
	This mount.cifs program has been built with the ability to run as a setuid root program disabled.
	mount.cifs has not been well audited for security holes. Therefore the Samba team does not recommend installing it as a setuid root program.

So two observations:
1 - The hints in NEWS (at least the fstab hint) won't work. (Or you should be more elaborate)
2 - The programm actually tells me "first do that" and after doing that it tells me "you cannot do that". That should be probably filed as another bug.
(Well, as it is kind-of already filed: #576314  New upstream 4.2 version available, the whole problem should be gone soon...)
