Afternoon....

I know this question has been asked hundreds of time's but I haven't been able to find a complete guide anywhere on the net!

I want to add my FC2 machines into my Active Directory environment and allow users to logon to the FC2 machines using thier Window's usernames.

Sounds simple.... but no!

I have achieved partial success. I have managed to setup Kerberos authentication and can authenticate ANY user against active directory using kinit USERNAME.
I have also setup Samba and can browse the shares on the Windows domain controller with out any issue. When I try to log on via GNOME to the box using a Windows username and password i can't. The below errors are logged.

Dec 17 17:11:53 linuxdisc gdm[3165]: nss_ldap: could not search LDAP server - Operations error

Dec 17 17:11:59 linuxdisc gdm-binary[3165]: Couldn't authenticate user

The even wierder thing is that I have managed to add this machine to the domain.

I have clearly missed a step or two but am at a loose end so I would appreciate any help anyone can offer!

Thanks

I'm not to familiar with Active Directory but I've run into similiar problems uing Open Afs. It turns out all it was was that I forgot to edit the gdm pam configuration file.

Ahh... That sounds like the cure.... I can only find documentation on the net about Suse Linux and it refers to pam_unix2.conf file which I can't find on FC2. Do you remember which file I need to edit, and or can you point me towards any doc's that might help?

Cheers

I found this which solved most of the problems.
http://www.redmondmag.com/columns/article.asp?EditorialsID=858

It doesn't mention the following changes to the smb.conf file

idmap backend = ldap:ldap://ldapserver.domain.com
ldap idmap suffix = dc=domain,dc=com
ldap admin dn = cn=Administrator,cn=Users,dc=domain,dc=com
ldap suffix = dc=domain,dc=com

Save the conf file and run "smbpasswd -w ADMIN_DN_PASSWORD"

Then run: (to get the Windows User's Passwords and Groups)
getent passwd
getent group

Add to /etc/pam.d/system-auth
session optional /lib/security/$ISA/pam_mkhomedir.so

And you're ready to go! You will now beable to login via X with your Windows user name and password
