The name of the column or an SQL expression that indicates the status of the user. The status is expressed by the combination of two bitfields shown below: bit 0 (0x01): if flagged, pam_mysql deems the account to be expired and returns PAM_ACCT_EXPIRED. That is, the account is supposed to no longer be available. Note this doesn’t mean that pam_mysql rejects further authentication operations. bit 1 (0x02): if flagged, pam_mysql deems the authentication token (password) to be expired and returns PAM_NEW_AUTHTOK_REQD. This ends up requiring that the user enter a new password.
