I have a working B2C Tenant that authenticates a MSAL mobile application as well as a web portal. It currently just has 1 identity provider which is 'Local Account'. I also have a separate enterprise Active Directory instance the rest of my organization uses and we want to incorporate that separate AD instance as an identity provider for our B2C Tenant. I see how to add other identity providers such as Google/FB but I was wondering if it's possible to add the external AD instance as a 'New OpenID Connect provider'? I've been trying to find documentation on whether or not this is possible but I'm a bit lost in the sauce. Thanks for any tips!
