Custom front end app authentication issues

We are seeing issues with a custom front end application which is used for CRM. Using on a client workstation we are continuously asked for reprompts of windows authentication however if we enter the correct password it is now working. The CRM front end server is also not registering that an incoming request has come in when looking at event viewer.

The issue began as soon as we configured Claims based authentication and IFD on our CRM server. Before this we didnt have the issue.

We had an issue similar with our development server however this was an issue relating to impersonation with our development server where a code change was required. We also made this change in our live environment and then setup and configured claims based authentication and IFD for CRM. Since doing this however the front end application is not working as expected.

When browsing on local server it seems to load the site ok but just not on a remote workstation's.

We did many hours of testing in our development environment but didnt get the issue there, so we have reverted our live version back to pre IFD and Claims and is working fine now.

I have restored our live environment in an isolated environment alongside our ADFS and AD servers so i can recreate the issue after setup of IFD and claims and the problem has appeared again.

So I am now at the point in amending config to see if I can get this working.

Any ideas on what this issue could be, I have a copy of our applicationhost.config for working and non working environments.

I believe this issue is to do with coding in the front end application, IIS config.

CRM 2013 back end is working as expected before and after claims and IFD setup.

Appreciate any help on this.

Many Thanks
