As required in [1] Some people migrating from previous versions of WildFly to the latest version are struggling with the migration of the RoleMapping login module. The equivalent of the RoleMapping login module is the mapped-role-mapper, which can achieve similar behavior.The main challenge comes from the fact that a properties file was previously used to map REALM roles to APPLICATION roles, and with mapped-role-mapper, this no longer seems possible. The proposal is to create a new role mapper based on a properties file to match REALM roles to APPLICATION roles. If you're interested and have time, please let me know, see the following Feature Issue and Proposal Feature Issue: https://github.com/wildfly/wildfly-proposals/issues/711 Proposal: https://github.com/wildfly/wildfly-proposals/pull/712 [1] https://issues.redhat.com/browse/WFLY-20384 Thank you Pedro Henrique Silva
