Bad password or user returns blank screen

Hi there,

The problem I'm having is that whenever a user tries to login and puts in a bad username or password, the program experiences a bind problem (this is in the watchdog):

ldap_bind(): Unable to bind to server: Invalid credentials in /var/www/html/modules/ldap_integration.module on line 408.

and then displays a blank screen with this in the address line "http://knowledge.sriconsulting.com/?q=user/login&destination=front_page". The user doesn't see the "Sorry. Unrecognized username or password. Have you forgotten your password?" unless he goes back to the root page.

Any thoughts?

Thanks,

Vicki
