[Feature Request] MSAL Java support for CIAM custom authority

[bgavrilMS]

MSAL client type

Public, Confidential

Problem Statement

CIAM will support custom authorities, which will require MSAL to perform OIDC discovery of the endpoints.

Blocked until we have a test environment.

Proposed solution

Recommendation is for MSAL to add support to WithGenericAuthority for user flows (consider renaming to WithOidcAuthority).

Since this is a general-purpose mechanism, we should also try to use a non-Microsoft authority, such as Facebook or Google. Concern is that client_info missing will mess up token caching logic

Alternatives
