A Message From The Founder...

As the founder of Nagios, I'm asking for your help in a cause that's dear to my heart.

I'm launching a new project to help better the world by providing the information, ideas, and inspiration that I believe can improve the lives of people everywhere.

I know you're busy managing networks, but I would appreciate it if you would consider liking my Facebook page and showing your support for the content and messages I produce by sharing them with your friends and family.

You can learn more about my project by visiting Thank you for your time. I wish you all the best in your endeavors, whatever they may be.

Perl script to check if an LDAP account is about to expire.
It searches an LDAP tree for accounts and evaluates their `PWDLASTSET` value (if the `ACCOUNTEXPIRES` is not `0`, which would mean that the account does not expire).

The maximum age of a password is typically determined by your organisation (typically something like 1 or 3 years). You can set the max using the `--max-age` flag.
You need to provide the LDAP server URL using `--ldapserver` and the base DN, which hosts the accounts to check, using `--ldapbase`.

The warning and critical thresholds can be configured in seconds using `--warning` (default: `30*24*60*60` = 30 days) and `--critical` (default: `5*24*60*60` = 5 days).

Download the tool at [](/assets/resources/stuff/monitoring/ (or see [GitHub](
