Topic on Talk:LDAP hub/Migration from extension LDAPAuthentication

I am trying example 1

This function os returning nothing :

$wgAuthRemoteuserUserName = function() {

   $user = '';

   if( isset( $_SERVER[ 'REMOTE_USER' ] ) ) {

       $user = strtolower( $_SERVER[ 'REMOTE_USER' ] );

   }

   return $user;

};

Suggestions ?

So is $_SERVER[ 'REMOTE_USER' ] even set? If not, you might need to configure your webserver e.g. to use the Kerberos protocol (Apache: "mod_auth_kerb") for authentication.
