Hello,

I have initially implemented webparts using windows authentication mode. But now i have requirement to authenticate user using ADS (Active Directory), so for this i used forms authentication.

But I am getting the below error. Am I missing something.. please help..

Error:

Personalization is not enabled and/or modifiable. The Enabled property must be set to true, and a registered personalization provider must be selected. The current user must be granted the right to modify personalization state

When using Forms Authentications in your Application then be sure to set the following:

* In your web.config file set Authentication Mode to Forms

		<authentication mode="Forms"/>

Thanks Stevew, Vinz

I finally solved my problem by adding FormsAuthentication.SetAuthCookie method...

But now i m facing another problem. Everything works fine when I run my application from VS 20005. But when I hosted my application on IIS, it throws error :

The specified domain either does not exist or could not be contacted

I tried using Basic authentication, but it gives popup. I dont want this as I am already authenticating my user through active directory. Can you throw some light on this method.

You reply will be of great help!!

PS: I have set identity impersonate = true in my web.config

try checking the anonymous access within iis, this should be checked aswell as basic authentication

otherwise try this link

Hey Stevew,

I tried checking both anonymous and basic authentication but same error comes. And the link which you gave me is for Windows Server 2000, I forgot to tell you that currently I am working on Windows XP
