Radius server and Single-Sign On

Can Radius Server be considered as SSO (many applications to be authenticated only once) if I want to provide one authentication form many applications ?

Because in my organization they asked to buy RSA for SSO, and my suggestion that radius can do similar job to SSO,,,Any insight ?

Kindly for RSA see below:

With the PIX and IAS + AD you can have single sign on if you implement Client VPN for your users. PIX is a wonderful box to do that.

Go through this link;

http://www.cisco.com/en/US/products/sw/secursw/ps2120/products_configuration_example09186a00806de37e.shtml

It talks about how to setup PIX for VPN and authentication through IAS and AD

RSA SecureID basically is a secondary logon to ensure higher level of security and then you'll have to login to your local network (Windows AD for example) if you want to access resources present there.

But with Radius, you can integrate it in such a way that (normal practice), it authenticates against the users based on their user credentials (usually windows AD).

I would suggest RSA since it adds the authentication process two-fold which is better.

Thanks Rajesh.

Just to verify things, Are both ( Radius and SSO (if we do not take RSA in consideration)) authenticate an user once,  and them after that you can access all services ? because my interpretation (correct me if I am wrong) to what you have mentioned that the only difference between Radius and SSO is the authentication process two-fold ?

Yes. It only depends on the way you configure it. For example, a lot of companies just use Microsoft IAS server as radius server which in turn authenticate the user against the active directory. It is a free radius server that comes with MS software.
