ADFS Proxy Replacement on F5 BIG-IP

Hi Graham, we have deployed the solution accordingly, the ADFS proxy trust is established and we can see that on the virtual server. On the port 443 virtual server no cert authentication client SSL profile is being used currently but only the public certificate to do SSL offloading, however when we send a https request using the browser to /adfs/fs/federationserverservice.asmx directly to it the request is not being proxied towards the internal ADFS server.

For your information if we change the virtual server to performance layer 4 with ADFS proxy disabled the URL is accessible so there is no connectivity issue here.

How does the ADFS proxy work exactly? Does it need to receive a specific ADFS request before it proxies it to the internal ADFS server? Is there also a way to debug the ADFS proxy to have more details about what is going wrong?

Thanks,

Marvin
