GLAuth configuration requirement

GLAuth must have the anonymousdse_enabled configuration option set to true so that SSSD can anonymously inspect the GLAuth server’s root directory server agent service entry (RootDSE) before binding to the GLAuth server. If anonymousdse_enabled is not set to true, SSSD will fail to bind to the GLAuth server as GLAuth will disallow unauthenticated clients from inspecting its RootDSE.
