"This account is currently not available."
what does it mean?
i mean, not literally, i get this message when i start nagios as a service

[shell]>service nagios start
Starting network monitor: nagios
This account is currently not available.

nagios starts normally, and i think is working fine, but i have no idea why it keeps me saying that every time i start/restart nagios
