Using OIDC JWT access token to authenticate in Kerberos
#20756
I have a Keycloak realm with configured LDAP user federation provider. In this realm I also have a properly configured OIDC client for my application. Therefore, whenever user sends a request to my application, it receives JWT access token.
My application needs to communicate with other service, which require Kerberos authentication. The Kerberos is backed by the same LDAP as my Keycloak federation provider. Is it possible to use JWT Access token to communicate with the other service on behalf of the user using information, extracted from JWT token?
P.S.: I lack sophisticated knowledge of Keycloak and authentication protocols, so if there is a better place to ask this question, please guide me.
