# WSOD's and some undefined variable/index errors

 * Brand new WPMU install, this is the first plugin I’ve activated.
 * When I try to save the Connection Settings form with the “Test Connection” option
   enabled, it sends me to a blank page that only shows the WP side and top bars.
 * It does save the connection information to the database, so I tried logging in
   with an LDAP user and ended up at a completely white screen.
 * I have WP’s debug turned on, and I have php logging to syslog. Nothing is logged
   for the white screens.
 * On the General Settings form php logs this to syslog:
 *     ```

 * When I save the Attribute Mapping form, this is logged:

 * I recently took this little project over for Dave (original poster). The original
   problem seems to have evaporated all on its own, however, the plugin uses a number
   of deprecated WP functions as well as a load of undefined index errors if your
   server is set up to show errors for them. If anyone would like a “fixed” copy
   of the plugin (wpmu-ldap_4.0.2), as well as a little about what I saw and fixed,
   it can be found [here](http://www.fotan.net/wpmu-ldap-plugin-fixes/)…
