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.
