We have a number of custom administrative tools that we're moving into a separate, internal-only, Web site.
Currently the applications use their own ASP.NET authentication tables, but it would be ideal to leverage the information contained within iMIS directly. Not single-sign on, but sign-on validating against iMIS.
Since we've already got the site setup, I wanted an addition that would impact the site as little as possible. For that reason, I decided to first look at the Membership Web services - methods returned by the service and some detail on http://www.imiscommunity.com/use_the_membership_web_service as well - and see if we could successfully leverage that.
