See this bug in Ubuntu:

and the related bug in Debian:

This is an intentional change in behaviour for security reasons. Instead of using mount with the setuid bit set you might want to run it using sudo.

For me, adding the sec=ntlmv2 parameter works.

Example:

sudo mount //server/share /localdirectory -o user=username,domain=WORKGROUP,sec=ntlmv2,iocharset=utf8

I use the smbfs tools package to mount my SMB shares. I wrote a quick script to mount the share:
```
#!/bin/sh
/usr/bin/smbmount "\\\\somehost.local\\hostshare" /media/hostshare -o user=smbuser,dom=WORKGROUP,uid=localuser,gid=localgroup
```
This script used to work in 9.10 when called by the "localuser" account, but in my fresh-installed 10.04 it fails giving me the error:
```
mount error(1): Operation not permitted
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)
```
The /media/hostshare directory is empty and has these perms:
```
drwxrwxr-x  2 localuser localgroup 4096 2010-12-12 12:04 hostshare/
```
The "localuser" is in these groups:
```
localgroup adm dialout cdrom plugdev lpadmin admin sambashare
```
Any idea what is going on here? Google seems to suggest that the "sticky" bit needs to be set on /sbin/mount.cifs /sbin/mount.smbfs and /sbin/umount.cifs

Is this a bug?

Nope the windows box is unmodified, the only difference was the update to Ubuntu. I'll give the configuration change a test.
