hi, i created set of custom policies in AD B2C to integrate use of OKTA as external IdP from B2C. I can see in SAML tracer I am getting back successful SAML response back to B2C but then Microsoft throws an error:
AADSTS50107: The requested federation realm object 'http://www.okta.com/e....8' does not exist.
The only areas that I suspect could be wrong is either specifying SSO URL as 'https://login.microsoftonline.com/login.srf'
and Audience URI as 'https://login.microsoftonline.com/{tenant id}/' or missing some attributes mapping.
Has anyone succeeded in doing this?
Thank you
Mark
