COMTI Security Override Fails If UserID or Password Is Longer than 10 Characters

View products that this article applies to.

Symptoms

COM Transaction Integrator (COMTI) applications that use the explicit security override feature to supply a userID and a password to COMTI generate the following error message when a userID or a password that is longer than 10 characters is submitted.
HRESULT=0x800706BE
Automation error. The remote procedure call failed.

Cause

The internal buffer sizes that COMTI uses for userID and password are limited to 10 bytes. However, there is no automatic test to make sure that this character length is not exceeded.

Resolution

To resolve this problem, obtain the latest service pack for Host Integration Server 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

COMTI now performs a test to make sure that the userID and password are 10 characters or fewer. If either value is longer than 10 characters, COMTI generates a 1419 error, which indicates that an authentication failure occurred.

This error will appear in the event logs as follows:
Event Type: Error
Event Source: COMTI
Event Category: General
Event ID: 102

Description:
(102) COM Transaction Integrator reported the following exception to the client:

Component: CICS_LINK.CedarBank.1

Exception description:
(1419) The LU 6.2 user ID or password were not valid for host.

If you are using Host Integration Server 2000 integrated host security, contact the system administrator.
