webserver_auth generates errors with og organic_groups

Server - Win2003 SP1 fully patched iis6
Clients - WinXP SP2 fully patched ie6

When using og (4/27/06 version) and webserver_auth, when a new user accesses the site for the first time, the account gets auto created properly, but numerous error messages appear on the screen. At the top of the browser window,

Notice: Trying to get property of non-object in D:\drupal-4.7.0-rc3\includes\bootstrap.inc on line 630

In the content block:

warning: array_keys() [function.array-keys]: The first argument should be an array in D:\drupal-4.7.0-rc3\modules\user.module on line 348.
warning: implode() [function.implode]: Bad arguments. in D:\drupal-4.7.0-rc3\modules\user.module on line 348.
user warning: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ')' at line 1 query: SELECT DISTINCT(p.perm) FROM role r INNER JOIN permission p ON p.rid = r.rid WHERE r.rid IN () in D:\drupal-4.7.0-rc3\includes\database.mysqli.inc on line 121.

Refreshing the browser window makes all the errors go away, and the user seems to be created properly.

I deleted the auto-created user in drupal, and the errors re-appearred when that active directory user once again used drupal.

Thanks,
Dusty
