You can authenticate Chat Service users using
either of these two methods:
Chat Service clear-text
authentication. With Chat Service clear-text
authentication, users are authenticated by their unencrypted chat
client password, which is sent to the server by way of the
Pass command. This is the least secure method of
Microsoft Windows 2000 Security
Service Provider Interface (SSPI). The
SSPI allows an application to use various
security models available on a computer or network without changing
the interface to the security system. A security provider is
contained in a dynamic-link library (DLL) that implements the SSPI
by making one or more security packages available to applications.
Each security package provides mappings between an application's
SSPI function calls and an actual security model's functions.
The chat client begins authentication with the server using the
Auth command. User credentials are encrypted and sent over
to the server.
On the Start menu, point to
Programs, point to Microsoft Exchange, and then click
Navigate to the
Chat Community where you want to authenticate users using
the SSPI package.
Right-click the chat community name, and then click
On the community's Authentication tab, clear the
Anonymous access check box, and then select the Windows
Security Package check box.
Note In order to begin
authentication, the SSPI package on the server must be compatible
with the chat client. The SSPI package that your server supports is
reported to the chat client using the Ircx or Isircx
