XFOR: MBS: Banned Chat Users Regain Access w/ Authentication (166722)
The information in this article applies to:
- Microsoft Commercial Internet System 1.0
This article was previously published under Q166722 SYMPTOMS
Membership Broker System (MBS) users who have been banned from an Internet
Chat Server (ICS) Service Pack 1 (SP1) chat can end their session, start a
new session and, regain entry to the chat from which they have been
banned. The banned users regain entry by adding a space after their user
name when authenticating.
CAUSE
When the authentication request comes in, the user name is stored in the
SSPI filter as received from the client. Although the Broker service will
strip off any spaces prior to submitting the name to the back end, allowing
normal authentication, external calls for this piece of data take it from
the filter area (as received).
STATUS
Microsoft has confirmed this to be a problem in Microsoft Commercial
Internet System version 1.0. This problem has been corrected in the
latest U.S. Service Pack for Microsoft Commercial Internet System
version 1.0. For information on obtaining the Service Pack, query
