User Authentication "Object Reference" Error

Hi Telerik team,

Here is the error

It occurs after I change "User Authentication" mode from "Form" to "Claims-based".
Please let me know how to resolve it as I cannot access to administration of the website.

Thank You..

Hello,

In order to switch to claims-based authentication you have to follow the description in our Sitefnity document.

All the best,

Here is the error if I use that approach.

Please let me know if you have other options to deal with current issue.
Recently I cannot access to back-end or Sitefinity administration.

Is there any way to get access sitefinity backend apart from using (site address/Sitefinity) to make some changes in setting?

Thanks and Regards,

Hi,
I was working on sitefinity 4.4 and upgrade to 5.
Then I made changes in Login function. I didn't notice that I was with "Form" authentication or "Claim-based" authentication.
Since I realized I was in "Form" authentication, I changed to "Claim-based", then I got the previous errors.

However, I have solution as below;
1) Create pure Sitefinity 5 project with newly set up database and so on...
2) Check User Authentication is "Claim-based"
3) Check web.config includes claim-based related configuration (such as <microsoft.Identity ...>)
4) Copy the web.config to the previous project web.config

It works! for me.
Let me know if you have better approach or if my solution has some inappropriate flow.

Thanks.
