Hi has anyone had any experience with setting up an OpenID server. http://openid.net/developers/libraries/.

Basically I want to implement an single login across multiple domains & sites.
I was thinking the PHP OpenID Library http://www.janrain.com/openid-enabled.
Alternative solutions welcome.

Currently running php5, plesk 10, centOS etc etc.

Thanks

Are you sure you need to host your own OpenID Provider? Most people already have multiple OpenIDs. Google, Yahoo, Blogger, Flickr, MySpace, WordPress.com and AOL accounts for instance can all be used for OpenID (see http://openid.net/get-an-openid/ ).

Hi Bruen,

I have a network of sites which are content interlinked. ie if you place an ad on one it appears in some of the others. They all run off different domains and some are hosted on other servers. What I need is a solution which allows users to log into one site and then automatically be logged into others when they visit. I also need to manage the users personal data etc with the ability to ban users, manage email lists, that sort of thing. Basically a single sign on (SSO).

So far I am looking at 3 options.
1. Build my own
2. OpenID
3. LASSO http://lasso.entrouvert.org/

I did read this article here http://www.dynamicalsoftware.com/news/?p=18 which is leading me to option 1 but I am lazy so looking for an existing solution.

Banning users and managing e-mail lists don't sound like typical features of a single sign on solution. They're certainly not things OpenID is going to give you, OpenID is just an authentication mechanism. Another option for SSO might be CAS: http://www.jasig.org/cas

But you definitely need more than just an authentication mechanism for the management features you're looking for.
