Hmmm, this indicates that smbclient was built wuth SSL support ...
Are you sure you were connecting to a Samba server? This is the sort of
response you would expect from a Win9X client when you connect to it with
the wrong NetBIOS name, but not from Samba ...
What does the Samba log files say?
Well, this is not going to be an issue until you get a NetBIOS session
going. However, you have to create this file and add users to is.
You can use the smbpasswd command to add users to the smbpasswd file, but
only for users that already exist in the /etc/passwd file.
