[Samba] Authenticating with Active Directory

[Jociel Andrade]

Hi all,

I need to authenticate Active Directory users in Solaris. I wrote a program
to do it using smbclient.a lib, but the method Valid_User is returning aways
the code 1 (Network Error). The program is in attachment.

When I use the following code, the user is sucessfully authenticated:
smbclient '\\192.168.0.20\downloads' -W adteste -U dmadmin%Senha123

But, this command log in the machine. I need a program that returns TRUE for
valid username/password and FALSE, otherwise. Can somebody help me?

Thanks in advance,
Jociel
