I am trying to configure a fresh minimal install of Centos 6 (Redhat 6) to authenticate against my companies Active Directory. I apologize if this is a basic question but I have been reading many how-to articles and I am very confused as to how to do this. Each article seems to describe a different method for accomplishing the same thing. Some include Kerberos others seem to simply say all i need is a pam_ldap module and nsswitch. I have followed a few but have not had luck and some how-to articles seem out of date as they mention non existent config files or the config files don't relate to the packages they tell me to install. Because I am to the point of just spinning my wheels I came here to ask for help. Any input would be greatly appreciated. What packages are needed to get this working? What are the options for setting this up?
One how to I have tried to follow was this one. http://wiki.freaks-unidos.net/linux%...e-linux-client
Which seems very simple but the ldap.conf does not exist until I installed the openldap-clients package with yum. That package however was not mentioned in the client. After installing I did edit that file and also tried editing the pam_ldap.conf as it seemed like the correct file to edit but I still cannot su - <ad_user>.
I have linux experience and some ldap/ad experience but I have never configured something like this before. Currently we have a set of linux machines that do authenticate against our AD instance but they were made by a consultant who set them up a very long time ago. So I do know its possible to do with our AD server. There are tons of mis-configured things on those machines and they are very out of date. Hence I am creating a new base template and then we will re build all those machines onto instances of that template.
