Alternative hostname for ADFS proxy possible?

Dear Community,

 

I have setuped a ADFS server with "adfs.customer.com" and a ADFS proxy, who also externally listening on this URL.

 

Here is my question: Can I configure an additional "external" URL like "adfs.bla.com" in the ADFS proxy so, that its listening to incoming requests and redirect it to adfs.customer.com?

 

Thanks

André

    Hi! 

    The short answer is no, the ADFS farm and WAP (ADFS proxys) use the same namespace when the farm is created, in your case adfs.customer.com. It's not possible to include multiple namespaces/URLs in a single ADFS farm since this would cause issues with token issuance and signing etc. 

    Recommended workaround: 

    If the use case of having a second external URL to point to your WAP (ADFS proxy) is primarily to give your customers users an easier time to navigate then there are two ways you could take, where the first one is the easiest

    1: Create a CNAME record in your public DNS that points adfs.bla.com to adfs.customer.com. This will redirect users to adfs.customer.com when they browse to adfs.bla.com 

     

    2: Set up a reverse proxy between the internet and your WAP (ADFS Proxy) that is configured with its own SSL cert and DNS records for adfs.bla.com that will then proxy requests down to the WAP (ADFS Proxy) on adfs.customer.com. 

     

    If this helps you feel free to mark my reply as a solution. Otherwise let me know if we should brainstorm further :) 

     

    Kind Regards
