samba - Jul 2008 - smbclient ( 3.0.31 ) can not connect to 3.2.0 server and vice versa

This is getting real tough to debug.

titan : Solaris 8 running samba 3.0.31
aequitas : OpenSolaris running samba 3.2.0

I can do basics test just fine :

But I can not connect to a [tmp] share on the 3.2.0 server.
The share [tmp] is defined thus :

[tmp]
comment = temporary files
path = /tmp
read only = yes

attempt to connect to it fail :

I try the reverse from the machine running 3.2.0 [ hostname aequitas ]
and I get a similar result

I have a complete trace of the packet traffic.

3.2.0 client attempts to connect to a chare on the 3.0.31 server :

I'm baffled.
