Using GroupWise Messenger 2.0.0.

When a user logs in they receive the following error:
"Please enter a valid User ID and Password."

The Messenger Agent displays this error:
SPL Login failed [0xAE11]: <username> - DDC: Original password is not

I have narrowed it down to the password for this user contains a ".". If
I change user changes their password to not have a ".", they can login.
I have quite a few users with special characters in their GroupWise
passwords. Is there a patch to resolve this issue?
