I am on ADFS 2016 and I would like to bypass ADFS login page and use RESTful API to authenticate users stored in an LDAP Directory (Declared as Local Claims Provider).
SAML 2.0 : apparently not possible to use REST API. =>Can you confirm this fact, please?
OpenID Connect : only ROPC (Resource Owner Password Credentials) seems OK.
With ROPC, I can obtain an Access and an ID Token using AD Account Store.
But I can't use my Local Claims Provider to authenticate users.
Do you know if there is a specific configuration or parameter to do this?
My configuration :
LDAP Local Claims Provider
OpenID Connect with ROPC flow
Note : With an authorization Code flow, I'm redirected to ADFS Login page where I can choose my Local Claims Provider and the authentication is OK.
Thanks by advance for your help.
