--development exec dbo.aspnet_Membership_GetPasswordWithFormat @ApplicationName=N'/Merch',@UserName=N'danielm',@UpdateLastLoginActivityDate=1,@CurrentTimeUtc='2008-08-05 18:41:39:430' --production exec dbo.aspnet_Membership_GetPasswordWithFormat @ApplicationName=N'/',@UserName=N'danielm',@UpdateLastLoginActivityDate=1,@CurrentTimeUtc='2008-08-05 18:45:17:710'As you can see the @ApplicationName parameter is empty on the production server and eventually the query is not able to validate any users. Again this is only a case when I run this application off of the production server.
