A list of account expiring in less than x days is displayed.
This plugin works only on Linux.
This nagios plugin checks the password expiration using the command chage.
The user running this plugin (nagios) must be allowed to run chage under root user
This implies to add an authorization via sudoer config file.
As an example, this is the file i added under /etc/sudoers.d directory :
#-------------------
User_Alias NAGIOS = nagios
NAGIOS ALL = NOPASSWD: /usr/bin/chage -l *
Defaults:NAGIOS !requiretty
#-------------------
The output is the following :
- PASSWD_EXPIRATION OK - ALL VALUES ARE OK!, Excluded account(s): [none]
- PASSWD_EXPIRATION CRITICAL - Exp < 5j:[root], Excluded account(s): [none]
- PASSWD_EXPIRATION WARNING - Exp < 6j:[accnt01, accnt02], Excluded account(s): [none]

Script works, but it has limitations as below:
- Warning is always overridden by critical value
- It can list only users with exact critical value. That is if password expiry days is 6 and critical value is set to 6, it will list username, but if expiry days is 5 and critical value, 6, it won't list username; only shows Critical status.
- To improve script more, you can include an option to "include" (same as exclude) users option
