I’ve posted a question to the Datapower external newsgroup asking about how Siteminder can be used to authenticate users. The documentation is pretty thin on the subject.
Basically, i have a username and password that I’d like Siteminder to authenticate. I’m sure that Datapower invokes a URL and posts the information to the given URI. It then inspects the response cookie and determines if Siteminder was successful.
The usual Siteminder usage pattern is for someone to hit a page with a web browser and then be issued a challenge.. So it’s possible Siteminder requires this step into order to validate.
