Grid Users are the users that create and deploy applications. You can use the graphical user interface or perform the required actions using the command line interface.

Login Brute-Force Attack Prevention
Configure users and their access after you install the grid. Grids have the following types of users:
The administrators have their SSH keys installed on the grid as part of the installation process and are identified only by their SSH key. The same SSH key cannot be used for regular grid users. Use the CA AppLogic installer to add and remove users. For information about configuring users or updating the administrator access keys for the grid, see the CA AppLogic BFC User Guide.
To significantly reduce the effectiveness of brute-force password guessing attacks, CA AppLogic prohibits users from repeatedly testing whether a name/password combination is correct by preventing the user from logging into the GUI after incorrectly entering a password 5 times. When a user incorrectly enters a user name or password 5 times, the user is locked out for 5 minutes and on subsequent 5 unsuccessful attempts, the user is locked out for 1 hour.
When a user is locked out, he is prevented from logging into the GUI even if a valid user name and password is provided until the timeout period has expired. In this situation, a grid administrator or another grid user that has access to the grid may unlock the user account using the 'user unlock' command. You can also see how much time a locked out user has remaining for their next login attempt by using the 'user info' command.
