I am trying to use OAM(Oracle Access Manager) as a single sign on in SharePoint 2019 where I am using OAMSSO as a idp and AD as a Service provider. For this in AD I have added Claim provider Trust for oamsso metadata also add claim issuance as is from NameID to EMAil ID and also added Relying party trust for OAMSSO fed url with LDAP claim issuance from EMAIL to EMAIL but while accessing on SharePoint 2019 it is authenticating and after that I am getting below error.

My Question is OAM sending token using SAML2.0, is it supporting in SharePoint 2019? and My SharePoint application is running already using windows users permission so Can I map the same user coming from OAMSSO logged in user ?
