MIM 2016: Continuous prompting for credentials on the MIM Portal


Here is what I have done

  1. I have installed the MIM Portal. I can access it at http://tlkmimserver/identitymanagement
  2. I have an alternate name for my server in DNS called tlkiam.tlkenterprise.net. The name “tlkiam” is the name I will make public
  3. I added a certificate to IIS for ssl. The cert is bound to the name tlkiam.tlkenterprise.net

Now when I go to the MIM Portal, I get prompted for credentials after about 10 minutes. If I click cancel several times then I can access the webpage. What is missing?

  3. Click Edit Public url
  4. Select MIM Portal Collection
  5. Enter “https://tlkiam.tlkenterprise.net”
  6. click save

Now add other mappings to this same public url, like
