[CentOS] CentOS 5.4 x86_64 authenticating against AD (Server 2008r2)

Hey All,

Just wondering if any of you have been able to setup CentOS 5.4 to authenticate against AD on a Server 2008r2 Domain Controller. I am trying to complete this particular setup however I have run into some difficulties such as not being able to lookup domain users via getent passwd. 

Thanks for your input,

Dan
