How to Configure Single sign on in a web application

Hi ,

Can any one tell me how to configure single sign on in a web application.

I heard from someone, that it can be configured in a xml.

Can anyone help in this regards

Thanks

That depends on the server you're using; the instructions for Tomcat are here. Being server-specific it can't be part of the web.xml file (whose contents are standardized).

Since this is an area that's not standardized it's not part of the SCWCD exam; thus I'm moving it to a more appropriate forum.
