UC_USER_LOGON - Single Logon

This Variable (VARA) object allows you to define whether automatic logon (Single Logon) is allowed. It is supplied in the system client 0000 and its settings apply to the whole Automation Engine system.

Access to the operating system is granted by specifying a valid user ID and password. However, if UC_USER_LOGON is enabled, the system checks if the Client has a Users object and, if so, it logs on automatically. For more information, see User (USER).

Note: When Single Logon is enabled, access control is shifted to the OS of the browser. Unattended screens can become a security risk and must therefore be avoided by using the relevant operating system.

Single Logon can also be used for CallAPIs, thus avoiding storing passwords in programs or procedures. Therefore, no changes are required when the password is changed. For more information, see CallAPI Overview.

This variable includes the following keys:

  • Key: WinNT

    Value: AUTO

    Restart required: No

  • Key: UNIX

    Value: AUTO

    Restart required: No

  • Key: LINUX

    Value: AUTO

    Restart required: No

  • Key: Call

    Value: AUTO

    Restart required: No

Enabling Single Logon

The following steps are required to enable Single Logon:

  1. Log on to system client 0000.

  2. Specify the keys for your operating systems in the UC_USER_LOGON variable.

  3. Define the relevant Client and User object.

    Note: The User object name must be the same as the one used for logging on to the OS.

    Example

    For Windows:

    • User name: Smith
    • Domain: DEV

    In this case, the name of the User object should be SMITH/DEV.
