I have just upgraded from 3.5.5 to 3.7.2 and now this has broken the site and no longer able to SSO.
ERROR:
No authenticationScheme was specified, and there was no DefaultChallengeScheme found. The default schemes can be set using either AddAuthentication(string defaultScheme) or AddAuthentication(Action configureOptions).
We’re going to release a 3.6.5 version of PSU that contains the CVE fix while we run down issues with authentication.
If you are having problems with PSU 3.7.x please open a ticket with support@ironmansoftware.com so we can address it. In the meantime, you will be able to update to 3.6.5 to patch the CVE.
Greeetings. I’m experiencing this issue after a several-version upgrade on our test PU server. We tried version 3.7.10 and see the same issue on startup where the message “No authenticationScheme was specified, and there was no DefaultChallengeScheme found.” appears when opening the site. (also appears as exception in log file).
Any movement on this known issue since 3.7.2?
