Looking for a PHP SSO (single sign-on) system

[guarriman]

Hi.

I'm looking for a SSO system in order to allow users to authenticate once and gain access to all my websites.

Do you have experience with one built with PHP?

Thank you very much.

You may want to consider something like OpenId. Never used it myself but it is meant for exactly this type of situation.

Read through [openid.net...] for more information.
