Using the Redirector :: The Serial/IP Control Panel
If the serial device server requires a login, the check box User Credentials From must be selected, otherwise it should not be selected.
When User Credentials From is selected, the redirector waits for the serial device server to prompt for a username and password. The virtual COM port can not be used by the application until the login sequence completes successfully.
In the Serial/IP Control Panel:
Select a virtual COM port.
Check the Use Credentials From checkbox.
In the drop-down list, select a source for the credentials.
These settings will be used the next time this virtual COM port is opened.
The redirector does not check for a login prompt from the server.
The redirector takes the credentials from Username and Password fields below.
These credentials are always used for this virtual COM port.
The redirector obtains values for the username and password each time a Windows login occurs.
The redirector has no username or password until the next Windows login.
If the Advanced Option Include Domain in Windows Credentials is enabled, which it is by default, the redirector pre-prepends the current Windows domain to the username before sending to the server.
Note: This option is not available in Windows 98/95/Me or multi-user operating systems.
Each time a user logs into Windows, the redirector displays a window requesting a username and password to be used while this user is logged in.
To enter credentials immediately, click Prompt Now.
Note: This option is not available for multi-user operating systems, such as Microsoft Terminal Services and Citrix MetaFrame Access Suite.
If a user is not logged in at the time a COM port is opened, the redirector proceeds as if Use Credentials From was not checked.
Each time an application opens this virtual COM port, the redirector displays a window requesting a username and password to be used.
These credentials are used once, for this specific use of the virtual COM port.
If a user is not logged in at the time a COM port is opened, the redirector proceeds as if Use Credentials From was not checked.
When the application opens the virtual COM port:
The redirector suspends the application.
The redirector presents a dialog box that identifies the COM port and contains entry fields for user name and password.
If the user clicks "OK", the redirector passes those credentials to the server.
If the user clicks "Cancel", or does not click "OK" within 60 seconds, the redirector proceeds as if no credentials are required for this connection.
The redirector waits for its connection to the server to become operational.
The redirector resumes the application.
Note: This option is not available for Windows 98/95/Me or for multi-user operating systems, such as Microsoft Terminal Services and Citrix MetaFrame Access Suite.
Remember that the redirector just supplies the credentials, while the server processes them to determine whether the user will be allowed. Various types of serial device servers have differing capabilities for validating credentials using methods such as:
Usernames and passwords that are internally configured in the server.
The Windows domain controller.
RADIUS servers.
One-time password authentication systems, such as SecureID.
The user authentication process introduces a brief delay in gaining access to the modem or serial device.
If the serial device server does not require a login and User Credentials From is selected, the redirector will not connect to the server successfully because it will wait indefinitely for a login prompt.
User Credentials will be disabled if only incoming connections are permitted.
