Found the problem. Some gremlin (probably one of the Samba config tools I
tried using) had added "auth methods = sam" to the smb.conf file. The
"guest" method was not listed so it wasn't being processed.

The man page for smb.conf is pretty clear about explaining this. Would be
good if the logger could spit up a statement too, like "guest processing
is not enabled" or the like.
