Recover From a Lockout or Bad Configuration

A change to the authentication framework configuration may inadvertently cause you to be locked out of the user interface. The Emergency One-time Login URL tool enables access by allowing you to create a one-time, session-limited login for any user from the command line. You will have continued access to your system in the event of lost passwords and/or failed Authentication Providers.

Note:  The Emergency One-time Login URL tool is applicable only when the new authentication framework is in use. This tool still executes and returns a ticket, but attempting to access the One Time Login page returns an error.

To recover from a Lockout or Bad Configuration when the Legacy Authentication Provider is Active, see Legacy Authentication Provider.

For security reasons, use of this tool is specifically logged in the Authentication Framework Logs. To learn more, see Authentication Logs.

How to Use the Emergency One-time Login URL Tool

This Emergency One-time Login URL Tool allows you to create a secure temporary session for any user account. This tool was requested by administrators and enables the Log In As... function.

The script is called AuthenticationOneTimeLogin.sh|bat and is located in the blackboard/tools/admin/ folder. The AuthenticationOneTimeLogin.sh|bat script takes the following arguments:

  • -u username: The username of the user to log in as.
  • -t minutes: The number of minutes before the session token expires. The default is 15 minutes.
  • -e entry code: The entry code that must be typed in a browser to authorize access. The default is an auto-generated hash.
