A customer reported that the nagios check UNIVENTION_SMBD fails since erratum 165 for UCS 4.2-1 has been installed. It looks like there are problem, when smbclient tries to log in with the user "guest".

The nagios check returns
"CRITICAL: smbclient failed: session setup failed: NT_STATUS_LOGON_FAILURE"

ok, smbclient -U guest -N -L hostname no longer works (samba regression?)
but smbclient  -N -L hostname

i replaced the command in nagios plugin check_univention_smbd (removed the -U paramter), but i did not change the nagios service/config, they still know/set/use the -U parameter (which is no longer used by the plugin)

this is not beautiful, but i wanted to change as few tings as possible and maybe the samba behavior changes again in the future ...
