Adding An Integer ID To Forms Authentication?

Nov 21, 2010

In the standard forms authentication, users are identified by a Guid. I want to give my users an UserId of type int (doesn't have to be the primary key, just something to do lookup's on).

Is it safe to add an additional column to the aspnet_users table, or should I create a new table which FKs to the UserId column and has a Unique column which generates the integer ID?

The later sounds like a bad performance hit to take just for the sake of an int!

EDIT I want to create URLs like those on stackoverflow. eg.[URL] where the User ID is an int. For that reason I don't want to use Guids.

C# - Forms Authentication Adding Additional Information Alongwith ReturnUrl?

Oct 12, 2010

With Forms Authentication when the app needs to redirect to sign-in page is there an event or any extensibility point that will let me do additional work to the request before it redirects to the sign-in page?

I would like to send additional information in the query string that could vary such that it wouldn't work to just statically embed that in the link in the loginUrl node in the web.config.

Edit: For clarification, I want to intercept the request prior to being redirected TO the login page.

Example:

<authentication mode="Forms">
<forms loginUrl="http://the/interwebs/login.aspx" timeout="2880"
enableCrossAppRedirects="true" />
</authentication>

And prior the user being redirected to http://the/interwebs/login.aspx I would like to be able to pack in query values so the url could end up something like http://the/interwebs/login.aspx?Action=Refresh

AJAX :: AutoCompleteExtender - Authentication Failure (forms Authentication)

Apr 15, 2010

'm using the AutoCompleteExtender from the AJAX control toolkit on my aspx page - I have it wired up to a WCF service that is returning a string array and everything works happily.

If I change my service definition to include a demand for the caller to be authenticated, like so:

<OperationContract(), PrincipalPermission(SecurityAction.Demand, Authenticated:=True)> _Public Function GetLookupValues(ByVal prefixText As String, ByVal count As Integer, ByVal contextKey As String) As String()

Then the autocomplete extender stops working, and I get an authentication error in the service. The service is set up to use ASPNetCompatibility mode, and I was hoping that the extender would pass the authentication credentials for my logged in user - does anyone know how to make this work?

Web Forms :: Tableadapter Doesn't Allow Null Integer Columns?

Mar 29, 2010

I have an sproc which selects data out of my table. The column can return integer or NULLs.

I get the 'failed to enable constraints error' when databinding. If I go to my tableadapter and select my column there is a NullValue property which has 'Throw Exception, Null, Empty'. If I try and unset the exception option it tells me only strings are allowed this. However the 'AllowDBNull' option is set to TRUE.

What is the alternative and will this be fixed in 2010?

Mixing Forms Authentication With Windows Authentication?

Feb 12, 2010

I have an (ASP.NET 3.5) intranet application which has been designed to use forms authentication (along with the default aspnet membership system). I also store additional information about users in another table which shares its primary key with the aspnet_users table.

For users who are part of our domain I store their domain account name in the secondary users table, and I want to automatically log in users whose domain account name matches a name stored in the table.

I have read the guides which are available - they're all from two years ago or more and assume that you are able to activate Windows Authentication on a separate login page that allows you to extract the domain account name. From what I can tell, though, this is not possible in IIS7 (the overall authentication method is applied on all pages and cannot be selectively deactivated, and both authentication methods can't be applied on the same page).

Is there a way of getting IIS to pass through the windows domain account name of the requesting user? I don't need proper AD authentication, just the domain name.

Ssl - How To Preserve Authentication For Forms Authentication Cookie

Aug 19, 2010

We have a non-SSL ASP.NET web app that allows a user to login (ASP forms authentication, inproc).

Once authenticated, we redirect their browser to an external, SSL secured page on another web site / domain altogether that we do not control.

The client is redirected back to a pre-configured url on our original http web app when done.

However, the customer is then asked to "re-login" again on our side which is undesired...

It seems the forms authentication cookie is destroyed when transitioning between HTTP and HTTPS and back again.

How can I keep the forms authentication cookie alive so that the customer does not have to re-authenticate on the round trip?
