Lock User account

Sometime and due to some circumstances like a user takes a long vacation and you don`t need to delete it, then you just lock his account.

Locking an account is an easy task to accomplish in an eye blink.

Simply invoke the following command:

# chuser account_locked=true <user_id>

The user_id is the “name of the user” or his/her “user id” (getting the user id is using the command id)

  For example to lock the user lpd ,run the following:

  # chuser account_locked=true lpd
