Can Create User But Can't Login


I just set up my site to use authentication.  I can create a use on the page and it automatically logs me in, but if I log out and try to log back in it keeps saying my login attempt was not successful.  I check the database and it is writing my user into the tables.  The password field is all weird but I am assuming that is some sort of hash.

Can anyone tell me where the best place to look for the problem is.  I am using the standard login control with the MySQLProviders if that helps at all.  

Forms Authentication -> login.aspx bypass and auto-create user?


Can I do the following, if I have 'this' within my web.config:

        <authentication mode="Forms">
            <forms loginUrl="Login.aspx" name=".ASPXFORMSAUTH" timeout="120"/>

        <authentication mode="Forms">

            <forms loginUrl="Login.aspx" name=".ASPXFORMSAUTH" timeout="120"/>


Cannot create a connection to data source ... Login failed for user: BUT not for all reports!


SQL Server 2008 using Report Builder v2.0  (Microsoft SQL Server Reporting Services Version 10.0.2531.0)

We have several reporting service apps with many reports in each one. There is a set of 4 reports that all report on similar info (but grouped differently) that can be run by me and other network administrators but not any "regular" users. On these reports only, they are getting "Cannot create a connection to data source ... Login failed for user...". As I've said there are other reports that regular users can run just fine!? ALL reports use the same Shared Connection Data Source on the server that is set up as Windows Integrated Security. The Data Source's Security allows Domain Users to browse.  

I've uploaded a test report to SSRS whos SQL is "SELECT 'test' as testField" and that's it: and is connected to this same Data Source and users still get the Login Failed error... even tried creating and using a new Data Source that points to the same SQL Server DB to no avail. Examining the rdl's XML doesn't reveal anything either.

Reporting Server is a different machine than the SQL Server DB holding the data.

The only clue is that working reports were created a year before now.

I thought this would be simple... Trying to create a login does an ajax check before submit


I have the standard .net login control that is working.  (Still learning .net after 15yrs of classic)

What I want to do is OnButtonClick run a javascript function (to do an ajax call to the db to check if login is valid or not) and if it returns true, then submit the form normally, else don't submit. The piece that I can't figure out, is how to correctly override the default click even to hit my JS routine and then submit the form properly afterwards.

Thanks ahead of time

Forms based users being prompted for windows authentication login for My Sites photos in user lists

Here's an issue I didn't see coming for our forms based authentication users. 

We have a web application extended to an external url to handle forms based authentication for users outside of our domain. Our setup looks like this...

Internal Users/Windows Authentication - moss.domain.com
External Users/Forms Based - mossext.domain.com
My Site for Internal Users - mysites.domain.com

When our forms based users are accessing user lists, or discussion pages that display user pictures, they are getting a windows authentication login for our internal users (mysites.domain.com) who have populated their my site with personal photo.

How do we fix this? 

Issue with Remember Me on User Login control


Hi everyone,

     I hope you can help me, I tried Google, but none of the solutions worked. Using VB.net and Membership, I have a login control in my master page with a remember me check box. When I check this box and login, some pages indicate that I am not logged in. If I go to another page, it will then indicate that I am still logged in. I have isolated one page that always indicates I am not logged in the first time I visit it, but if log in a second time and then go to it, it will finally recognize me as a user that is properly logged in. 

Some pages that this occurs on is in the top level, some pages are in a sub folder.

My MasterPage has the following Form Code:

<body bgcolor="#E0ECF9" topmargin="0" leftmargin="0">

    <form id="form1" runat="server">

My Aspx file has a troubleshooting label, several Gridviews and several DetailViews:

    <asp:Label ID="lblErRep" runat="server" Text=""></asp:Label>

My aspx.vb file has 1 line of code (Protec
