Authenticate the Command-Line User

You can use the Application Center command-line tool AC.exe, to partially administer an Application Center cluster without using the Microsoft Management Console (MMC) snap-in. This is particularly useful for scripting.

Command-line options might require user authentication. To use specific credentials for example, when connecting to a remote computer, use the parameters shown in the following procedure.

To authenticate a command-line user

  • From the command line, type

    AC LOADBALANCE /offline /member: server /username: user_name /password: password

    Where server is the remote computer to connect to.

    Where user_name is the user name to use for authentication. This can be of the form user_name or domain \ user_name.

    Where password is the password to use for authentication and is of the form {* | password}. For further security, entering an asterisk (*) causes the user to be prompted for the password. Each character entered is displayed as an asterisk (*).

    If either the user name or the password is not valid, the error message "Username or password not valid" is displayed. For scripting purposes, the return value is 1000 (AC_ERROR).

If you supply user credentials via the AT /username and /password parameters, they will be stored, unencrypted, in the schedule's associated .job file.
