Recommended Commercial RADIUS solution for Linux Authentication

I'm looking for a commercial RADIUS solution that Linux Servers can authenticate against. Specifically:

1) Primary purpose is for Linux user authentication
2) Is there any RADIUS solution that can replicate to other RADIUS servers, just like Microsoft Active Directory Servers can replicate to each other? This can even be a one way replication.
3) Preferably this RADIUS solution runs on Linux and not windows.
4) Preferably is a supported RADIUS solution, i.e. paid for product that we can get support on as needed. Unless there is a simple to use free version that doesn't require extensive learning to use.

Thanks!

Ehm. why Radius...., Radius (or more modern Diameter)  are meant for authentication to network equipment.
Radius is meant for one shot authentication authentication & authorisation details presented at once.....
Radius doesn't provide a home directory, uid, gid code etc.)

So i guess you mean LDAP authentication..., there are lots of tools available.
(openldap is the native solution, others do exist,  for commercial providers look for IPAM solutions).
LDAP != AD btw.   With LDAP the client system asks for a password at the central repository. AD authenticates with Kerberos.

Hi Noci,

As you can see, I don't know much about RADIUS and from your answer it looks like the better way to go for my purpose is some sort of commercial LDAP solution.

Do you have any suggestions for LDAP solutions other than Microsoft AD?

And can LDAP solutions replication to multiple servers like Microsoft AD can?

I found this, what do you think?

Samba 4+ can act as a stand-in for AD.   it is running an internal kerberos & LDAP engine.
Many of the IdM systems sold are linux based and employ Bind, Openldap, Kerberos etc. (and also can provide Radius for use by network equipment).
(I used the wrong abbreviation before IPAM is IP Address Management, IdM are Identity management systems.)

I have no opinion on "best" commercial systems.
I use openldap + phpldapadmin to manage a fairly small tree.
This question needs an answer!
