paranoid server security (G)
Some version of NT 4.x allow non-guest
users with a bad passowrd. When this option is enabled, samba will not
use a broken NT 4.x server as password server, but instead complain
to the logs and exit.
Disabling this option prevents Samba from making
this check, which involves deliberatly attempting a
bad logon to the remote server.
Default: paranoid server security = yes
