Hi,
One of our .net web applications is using Dynamics 365 CRM on-premise as a backend. Currently, the authentication type is NTLM Kerberos authentication. We have tried to change the authentication type to claim-based in the CRM deployment manager tool, for some reason claim based authentication didn't work, so we have disabled claim-based authentication in the CRM deployment manager. After these changes, the CRM application login is working fine but .net custom web applications are not working. It is throwing below error after entering user credentials. I have tried to debug this in visual studio code, it is working fine. However, I tried to access the application hosted under IIS that is not working. There are no changes with respect to the .net code. Could someone help me to give a solution for this?
We are using Dynamics 365 CRM on-premise version.
