Plus Pack features missing due to older version of MDAC on the server

This article applies to the following products:
     Messageware Plus Pack 2003

 

SYMPTOMS

Users are unable to see Plus Pack functionality in Outlook Web Access in environments with Integrated Authentication. The following event is logged in the Application log

Event Type: Error
Event Source: Kerberos
Event Category: None
Event ID: 4
Description: The kerberos client received a KRB_AP_ERR_MODIFIED error from the server host/tusdfsmosvr.tusd.local.  This indicates that the password used to encrypt the kerberos service ticket is different than that on the target server. Commonly, this is due to identically named  machine accounts in the target realm (SERVER NETBIOS NAME), and the client realm.   Please contact your system administrator.


RESOLUTION

This issue is a rare occurrence which is corrected by upgrading to the latest version of Microsoft Data Access Components (MDAC). To download the latest MDAC visit the Microsoft web site below
