Linux + GNU = Humans Enabled

In case you should ever be finding yourself having to configure your CentOS 5.8 GNU/Linux machines to allow active directoy windows users to login to them, this post will help. While there are a few ways to set this up, i.e., likewise-open (see beyondtrust.com), centrify (centrify.com), the built-in System, Authentication graphical controls in CentOS, etc., the method in this post focuses on touching just a few config files to enable active directory  authentication.

LDAP brings the UID/GID information (from the Unix tab in ad) for the user, and Kerberos provides for username/password authentication piece. With the default insta...

Fedora 6 LDAP / Kerberos Auth to Active Directory on Windows Srvr 2003 R2 Tested by Shannon VanWagner Problem Connecting Fedora 6 to a Windows Srvr 2003 R2 DC for auth and uid/gid sync with AD.

Create a user in AD to use for authenticating via LDAP from the Fedora 6 client. Make this user a primary member of Domain Guests for security. 3.) For any Win user that logs into the Fedora 6 machine, modify the "UNIX Attributes" tab for the user's account in AD. ...
