samba - May 1999 - Security related bug/issue ... or mis-configuration?

Morning...

	Attached are two files.  The first (smb.session) shows one user
connecting to two different shares on a remote server using *no*
password...

	The second is the smb.conf file found on that remote server,
running Solaris 2.6, and Samba 2.0.3 ...

	I'm *really* hoping that its something that we're overlooking as
far as configuration is concerned...or else there is one helluva large
hole in Samba :(

	Authentication, as shown, is to thor.acadiau.ca, which is an NT
server...

	Any help *much* appreciated...

Thanks...
