I tried to add role management capability to my production site by exporting the aspnet_roles and aspnet_usersinroles tables from my development machine to production through SQl Server 2005, and adding role manager to the web.config file. Now my users cannot log on, even though the user ID's and passwords they enter are correct and are stored properly in the aspnet_users table in production. The same code and data are in the provider tables and work fine on my dev machine. What might the problem be? Harry
