[Samba] samba with Linux and Windows clients

[Adriano Vasconcelos]

I don't autenticate linux in the samba server. The usernames are known but the passwd are invalid. It happend when try install the pamsmb and NIS. What I do? 

In the documentation, is necessary modify the autentication for no use MD5 ou Shadow passord when there are systems operations diferents. Is correct ?

Configuration:
Server - Freebsd - Samba 3
Client - Linux Mandrake 9.1 / Kurumim 2.12
