I am implementing ADFS in SP2013. Everything is working in SP except workflow manager. I found that when I execute a 2013 workflow using an NTLM account, it works. When I log in using ADFS, the workflow suspends with the following error:

"There has been an error authenticating the request.\";category=\"invalid_client\""]

I have read that WFM uses the UPN claim type to look up the user in UPA. We converted users to ADFS using the Email Address claim type. I suspect it can't find a match. Any ideas? Is there a way to tell WFM to us the email address?

Follow up: I tried to map the User Principle Name in the UPA to "mail" and ran a full sync with no success. Then I mapped the Claim Type Identifier property to "userPrincipleName", ran a full sync, and surprisingly that didn't work either. Is anyone aware if workflow manager even works with ADFS?

To troubleshoot the issue, check things below:

  1. Check the information about the error in the event log in the workflow manager server.

  2. Check if the User profile synchronization is started.

  3. Run a full synchronization of User Profile Application with ADFS users.

  4. Activate the “Workflows can use app permissions” feature in the site features.

  • Thanks Amy_SPWX, I did all that. Everything is working. I can even create and publish 2013 workflows using ADFS (SPD prompts me to select an authentication method) and run them under an ntlm account. I read in a post someone from Trevor Seward something about rehydrating WFM but I don't know what that means. I might have to open a support case with MS Commented Jan 26, 2018 at 13:27
  • Clarification: when I said everything is working I meant the items you listed in steps 1-4. Still getting the 401 error Commented Jan 26, 2018 at 16:18

I found out what my issue was. I had a UPA sync connection to AD for both the NTLM users and ADFS users, so I had two SP profiles for each user. When I delete the NTLM user profile for my account and tested a workflow, it worked. I planned on deleting the NTLM profiles and sync connection once the conversion and testing was complete. Didn't think it would affect anything leaving it there for the time being.
