Introduction

This is a simple Single Login Module.  The module allows a user can login to a portal by authenticating the user’s credentials against other portals within a DNN installation.  The user may bypass registration and verification processes.  For example, a user attempts to login to “Portal A” without registration before.  This module will authenticate the user’s credentials (username/password) against other portals.  If the authentication is successful in one of portals (let’s say “Portal B”), the user will be allowed to login to “Portal A” without processing registration and verification steps.   After the successful login, the user’s registration information and correspondingly named role will be copied from “Portal B” to “Portal A”.  For example, the user in “Portal B” has three security roles: “Registered Users”, “Subscribers”, and “Album Subscribers”.  Most likely, “Registered Users” and “Subscribers” security role will be added to the user in “Portal A” because they are default roles.    If “Album Subscribers” exists in “Portal A”, the user also will have this security role in “Portal A”.
