53xl2 (53xl2) asked a question.
I am running through the process defined here: https://help.okta.com/en/prod/Content/Topics/integrations/adfs-okta-int.htm however, I am running into an error stating "MSIS7065: There are no registered protocol handlers on path /adfs/oauth2/authorize/ to process the incoming request"
I see the error when ADFS attempts to load the Okta auth frame on the ADFS page.
I have configured Okta to use the MFA as a Service option (versus OpenID Connect), for what it is worth.
Any thoughts on how to troubleshoot or get past this issue?

I was going too fast and forgot some details:
Our engineers are currently working on internal tickets regarding this issue.
I do suggest opening an Okta Support ticket so to keep in touch with further updates regarding this.
Was this problem solved? I am getting the same error on Windows 2016 ADFS with Okta ADFS Adapter 1.7.10. SAML-based ADFS relying party trusts are working fine with it but not the OIDC-based applications.
Hello, same issue here.
Have you got any updates from Okta?
Hi, same issue here.
Any further findings here?
We wanted to secure vSphere Login via OKTA MFA Adapter and AD FS.
In the VMWare forum I found this article (however in reference with DUO): https://communities.vmware.com/t5/VMware-vCenter-Discussions/MFA-DUO-integration-with-ADFS-vSphere/td-p/2933416
Use OktaADFSAdapter-1.7.11 (or newer version if available). It must be configured in "MFA as a service" mode.
