We are trying to deploy Microsoft based self-service portal on our on-premise installation of CRM 365. With AD FS deployed we are getting authentication errors as follow: Invalid user name or password. The authentication endpoint Username was not found on the configured Secure Token Service! We are able to sign-in to the CRM through AD FS however the portal configuration tool gets this error with the same user and password. We spend a lot of time trying to find any help, however all of articles are related to the on-cloud version.
Your help would be greatly appreciated.
