[SM-PLUGINS] lockout plugin problems

[Alex <mys...@gm...>]

Hi,
I'm using a squirrelmail 1.4.23SVN snapshot and having trouble with
the lockout plugin. I had it configured on a test system many months
ago, and I thought it was working properly, but now it's not.

There are no php errors in the logs, and my configtest.php looks okay.
Squirrelmail otherwise works fine. I'm not sure how to further debug
this, and really hoped someone could help. I've configured
locked_out.php with my own text, and it's never printed. I've also
installed and enabled the compatibility plugin. The
lockout_plugin_login_failure_information.pref has old entries in it
where it once worked properly. squirrelmail_access_log has the failed
login entries, but there are no new entries in the
lockout_plugin_login_failure_information.pref file after trying and
failing to login $max_login_attempts times.

I've included my config.php below (using example.com)

$use_lockout_rules = 1;
$reverseLockout = '';
$at = '@';
$obey_x_forwarded_headers = 0;
$max_login_attempts = '6:10:30';
$max_login_attempts_per_IP = '';
$activate_CAPTCHA_after_failed_attempts = '';
$lockout_notification_addresses = 'gd...@ex...';
$log_violated_lockout_rules = 1;
$log_violated_max_user_logins = 1;
$log_violated_max_IP_logins = 0;
$log_CAPTCHA_enabled = 0;
$lockout_useSendmail = NULL;
$lockout_smtpServerAddress = NULL;
$lockout_smtpPort = NULL;
$lockout_sendmail_path = NULL;
$lockout_sendmail_args = NULL;
$lockout_pop_before_smtp = NULL;
$lockout_encode_header_key = NULL;
$lockout_smtp_auth_mech = NULL;
$lockout_smtp_sitewide_user = NULL;
$lockout_smtp_sitewide_pass = NULL;

Thanks,
Alex
