Configure Red Hat Linux as Radius client and Windows NPS server as radius server


Hi,

We have Windows NPS radius server running on windows server 2012, this radius server authenticates the clients against Active directory. I need to configure all linux servers as radius clients for authentication against this radius server and in turn active directory.

I am not very much familiar with Linux as well as Radius, I tried to search a lot with google, so any step by step guide would be much handy for me.

Thanks,
Balaji.

You need to configure the authentication subsystem to forward logon requests to the RADIUS server.

The subsystem in question is called PAM (Pluggable Authentication Modules), and the module you're looking for is pam_radius_auth. The module may very well be installed already (look in /usr/lib64/security or /usr/lib/security if this is a 32-bit system).

Please note that unless you can somehow coerce the Windows RADIUS server to return a Unix UID (which I strongly suspect can't be done), you will have to create the users locally; only the passwords will be fetched from AD. More seamless integration is possible using LDAP, Kerberos or Samba winbindd (or SSSD, so I've been told). PAM modules are available for all of these.

There are THOUSANDS of easily-found documents on Google that deal with Radius authentication between Linux and Windows. The documentation on the FreeRADIUS site is just one;
http://wiki.freeradius.org/guide/Fre...egration-HOWTO

We will gladly help you with specific questions, but asking us to type up 'step-by-step' guides, or hand you links is fairly rude. Please show some effort of your own.
