Issue/Introduction
With an incorrect VIP Security Code, LDAP users may be able to access VIP (Outlook Web Access) OWA.
Cause
Incorrect path is set in for owaauth.dll (VIP Integration Settings --> Authentication Configuration --> Plugin's URL Configuration)
Resolution
Do not use the full path of owaauth.dll (for example, C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\Owa\auth\owaauth.dll). Instead, use /owa/auth/owaauth.dll
After changing, perform an iisreset and check functionality.
