Manual:SessionManager and AuthManager/Troubleshooting

My provider does not appear in AuthManager's internal provider lists, even though it's listed in $wgAuthManagerAutoConfig

 * You might be changing  too late, after AuthManager has already been initialized. You should either use the   key in , a callback, or the PHP entry point of the extension. You should not use extension functions, they might run too late.
 * Some extension might still use the AuthPlugin interface and change . When that happens, AuthManager switches into backwards compatibility mode and skips loading primary providers (that's necessary since AuthPlugin extensions are not prepared to run alongside other authentication extensions).
