Principal role mapper for WildFly AvancedLdap login module

When using authentication via kerberos + LDAP on WildFly (i.e. using AvancedLdap login module), subjet contains (custom WildFly) principal with assigned roles. However, ISPN is missing proncipal role mapper for such use case and user has to implement his own mapper (like this one). It would be nice to have such mapper directly in ISPN, so that users don't have to write any custom code.
