Authentication passed Entering updateUser
Errors on the page after successful logon:
: 1 threads didn't exit PHP Notice: Undefined offset: 0 in D:\wiki\extensions\LdapAuthentication.php on line 1121
): 1 threads didn't exit
updateUser is called after group restriction checking. Most likely, the plugin isn't configured correctly. Are you trying to do nested group restriction, or (nested group) synchronization? Notice that the latter isn't currently supported...
The error you are getting is a bug, but isn't really affecting anything you are trying (yet...). Notice however, that the error is still likely due to mis-configuration; the bug isn't affecting functionality, it is just failing to cause the plugin to fail gracefully.
Btw, always use the current stable version of the plugin (currently 1.1f), unless specifically pointed to the alpha/beta version for a bug fix.
V/r,
