[Samba] Samba PDC not in network environment (Windows 7/8)

[Jörg Nissen]

Something I came across. Don't know if it is related. Trying to connect to a 
Windows 8 share from my PDC results in

cli_session_setup: NT1 session setup failed: NT_STATUS_INVALID_PARAMETER
session setup failed: NT_STATUS_INVALID_PARAMETER

when "client NTLMv2 auth = yes" set in smb.conf. "smbtree" executed by a domain 
admin user lists all shares on PDC and nas but only the name of the client.

Changing settings to

client NTLMv2 auth = no
client lanman auth = yes

gives access to shares on the Windows 8 client. "smbtree" lists all 
adminstrative shares (C$, D$, etc.) on Windows 8 client.

There are some entries in the samba logfile for client "JOGO" which seem to be 
problem related:
