Add a filtering RoleMapper implementation. ------------------------------------------ Key: ELY-889 URL: https://issues.jboss.org/browse/ELY-889 Project: WildFly Elytron Issue Type: Feature Request Components: Utils Reporter: Darran Lofthouse The RoleMapper APIs are built around querying one role at a time, however at times it may be desirable to obtain a set of roles an identity is a member of. To avoid iterating every role which depending on the configuration could be thousands backed by a remote store we should have a FilteringRoleMapper implementation that will allow any checks and iteration of the roles to be restricted to a finite set of acceptable roles.
