Options. Authentication settings

---

The Authentication tab of the Options dialog box allows you to set up authentication mode and contol how securely authorize users to allow them to establish connection with the communication server and enter to the IM network.

To open the Options dialog box click the  button on the toolbar or select the "Tools\Options..." item from the main menu or use the Ctrl+O hotkey.

Authetication settings

• "Simple" — This mode only matches user's Windows logon ID and account name on the communication server. No any other authorization is used.
  
  
• "Windows Authentication" — The communication server authenticates users using standard Windows Authentication (SSPI). This is the most preferred mode for domain networks.
  
  
• "Private login/password" — Use pair of private login name (IM account name) and password to authenticate users on the communication server.

Changing the authentication mode will disconnect all currently connected users to the server. Messaging clients will automatically reconnect to the IM server within 60 seconds or less using the new authentication mode.

You can also set up a different authentication method for each user account personally.

You can also set additional options related to user connections that do not depend on chosen authentication mode:

• "Allow concurrent connections for the same IM account" — Enable this option if you want to accept concurrent connections for the same IM account. The server will accept two or more users who connects and enters to the IM network with the same account name from differect computers/locations. All messages to that IM account name, such as private, group and news messages will be delivered to all connected users with the same name.
  
  
• "Forward messages sent by one to others to show in their conversations" — If concurrent connections from the same IM account are allowed then you can enable forwarding sent messages to all other users with the same account name currently connected to the communication server.

For example, 2 users, A and B with the "Administrator" account name are connected to the IM server from different computers. One of them (user A) sends an instant message to some user or on messaging group. That message will be also shown in the conversation dialog and Message History on another user (user B) even the message has been sent from another PC.
