[monit] Error: PAM is not supported ''

[Germán Bobr]

When i run monit i receive this error:

/etc/monitrc:228: Error: PAM is not supported ''

This is my monitrc file

set daemon  120
set logfile syslog facility log_daemon
set statefile /var/.monit.state
set eventqueue
    basedir /var/monit  # set the base directory where events will be 
stored
    slots 100
set httpd port 2812 and
    use address localhost  # only accept connection from localhost
    allow localhost        # allow localhost to connect to the server and
    allow admin:monit
    allow @monit

What am i doing wrong? :P

Thank you
