Hi all,

I had linux samba 3.0.10 running as PDC of my domain which does only 
for other linux samba boxes which are providing access to shares.
After upgrade of PDC to Debian Lenny + samba 3.2.5 I've lost guess 
access to the shares which are run by samba 3.0.x boxes,
while it works on samba 3.2.5 samba box. the scheme is like following :

                                                   _      [samba box 
3.0.10] <-------  (not working)
                                     (auth)   /                       
<<----- /                                                                
PDC [samba 3.5.2] 
                                                                                       client (guest access)
\                                                                    /
                                      (auth)  \_       [samba box 
(3.5.2] <------- (working)

on PDC in smb.conf regarding guest access i have :
map to guest = Bad User
guest account = pcguest
and pcguest unix account does exist.

on samba box's guest ok = yes is set .

in the logs of samba box  where it's working (3.0.10) , among many 
things , i could find :

[2011/03/16 20:37:41, 1] auth/auth_server.c:check_smbserver_security(373)
   password server * gave us guest only

which is not reported from 3.2.5 box.

Any help / advice would be highly appreciated.

best regards,
