Hi Sergey, for OIDC you can already do something like this via the Script Protocol Mapper which allows to compute the result value via JavaScript. See: - https://github.com/keycloak/keycloak/blob/master/services/src/main/java/o... - https://github.com/keycloak/keycloak/pull/4495 I didn't have the time yet to implement the same for the SAML protocol mapper, but there is a JIRA issue: https://issues.jboss.org/browse/KEYCLOAK-5520 Support for template interpolation via a dedicated protocol mapper would be nicer though, since it would allow for more concise mapper definitions.
