samba - Dec 2001 - security=domain

Hi everyone,

I am trying to use the domain security option on samba 2.2.2 on red hat
7.1
. Just works with security=server.  My PDC is an NT 3.51 (Service Pack
3).
Here is my smb.conf is :

[global]
        domain master = False
        dns proxy = No
        encrypt passwords = Yes
        name resolve order = lmhosts wins host bcast
        preferred master = no
        hosts allow = 192.168.
        password server = 192.168.1.100
        allow trusted domains = No
        security = domain
        local master = No
        server string = File Server - Linux RH 7.1 Samba 2.2.2
        workgroup = GRUPO
        netbios name = test.grupo.es

[Edusan]
     path = /home/admin/edusan
     browsable =yes
     writeable = yes
     valid users = edusan
     public = no
     create mask = 0755

It looks good for me and I was trying several things, but I can not make
to
work. Somebody knows if i missing something or ?

Thanks,

Eduardo
