Details

Caution:

This functionality is still experimental.

$wgAutocreatePolicy controls account auto-creation behavior when external authentication is enabled. (See $wgExternalAuthType and $wgExternalAuthConfig for details.)

$wgAutocreatePolicy can be set to one of three values:

• never - do not automatically create new accounts.
• login – create new accounts on user login. This is the default setting.
• view - not currently implemented. Will require the external database to support cookies and implies 'login'.
