[SOLVED] Need advice: remote login authentication

[engocoka]

Hi All,

I'm interested in establishing a computing lab for the CS major at my liberal arts college. I have a fair amount of single system Linux experience, but I am less familiar with system wide administration issues.

I'd like to have a setup where I have 20+ computers that authenticate their logins through a central server. In other words, a student could log into any of these machines, change his/her password, then walk across the room and log into the new machine with his/her new password. Somehow the client would get an authentication through the server Windows AD style.

I've done some googling on this and ran across lots of LDAP/AD/Kerberos HOWTOs, but the ones I encountered were geared toward getting Linux to authenticate with Windows servers. I also ran into PAM stuff, but it's not clear PAM itself is what I'm looking for.

Does anybody have any advice on what sort of configuration I should consider in this case on both the server and client end? Or, if I'm in the wrong forum, could you point me to the right one? I would greatly appreciate any help.

hi,

I would recommend going the LDAP approch, Windows AD is basically an ldap server as well. PAM provides pluggable authentication modules. One of those modules is libpam-ldap, when you have it installed on 20+ clients everybody would authenticate against the central ldap server. The package smbldap-tools provides the commands to change the password remotely.

Mind you, setting up the ldap authentication is not so easy. Below are the two articles/howto's that I used.

ldaptastic (http://times.usefulinc.com/2005/09/25-ldap)
OpenLDAPServer (https://help.ubuntu.com/community/OpenLDAPServer)

You need NIS, Novell, or Redhat Directory.

All directory systems are LDAP (X500) based.

Thank you both for your advice. It looks like LDAP what I was looking/hoping for.
