for Admin user it works, but I got this error for not Admin user:
Caused by: org.alfresco.repo.security.permissions.AccessDeniedException: Access Denied. You do not have the appropriate permissions to perform this operation.

why?

[dhalupa]

Isn't it obvious? Because you do not have permission to execute that method. Run the invocation of that method as admin user

AuthenticationUtil.runAs(new AuthenticationUtil.RunAsWork<Set<String>>() {
   public Set<String> doWork() throws Exception {
      return serviceRegistry.getAuthorityService().getAuthoritiesForUser("someUser");
   }
}, "admin");

Kind regards,

Denis
