> Default Elytron configuration assigns role "All" to every user during authentication. If a deployed application uses such the role name for a resource protection, then every authenticated user can access the protected resource. So the security is bypassed then.
> The problem is caused by workaround used for mapping "LoginPermission" to all users. It maps role "All" to the users first and then maps "LoginPermission" to this role.

> We have to make the default server configuration secure for users.
> *Suggestions for improvement:*
> * the {{LoginPermission}} mapping should be implicit so everybody has it by default - without specifying it in the server configuration; users should only define cases when they don't want the permission to be assigned to some principals/roles
> * constant permission mapper should exist in Elytron subsystem (similar to {{constant-role-mapper}}) so the custom permission can be mapped without workarounds through role-mappings
