Theme change causes LDAP group assignment error.

When I added the following code to the garland theme (to hide the log message field), the ldap module no longer assigned a role based on ldap group.

function phptemplate_node_form($form) {
// Remove 'Log message' text area
$form['log']['#access'] = FALSE;
return drupal_render($form);
}

When I used the formfilter (http://drupal.org/project/formfilter) module to hide the log message field the result was the same. I have to say I am stymied. Does anybody have any idea why this would have this type of effect on the ldap module? I am running drupal 5.14 and ldap 5.13. Any help you be appriciated as I would like to be able to hide the form box.
