# ipa-epn(1)

Send expiring password notifications

## NAME

ipa-epn - Send expiring password notifications

## SYNOPSIS

ipa-epn \[options\]

## DESCRIPTION

ipa-epn provides a method to warn users via email that their IPA account password is about to expire.

It can be used in dry-run mode which is recommended during setup. The output is always JSON in this case.

It can also be launched daily by its systemd timer. In this case it will parse its configuration file [epn.conf(5)](/epn.conf/5.md) and send an email to users whose passwords are expiring within the defined future date ranges.

See the OPTIONS section below and the [epn.conf(5)](/epn.conf/5.md) man page on how to configure the tool.

## OPTIONS

- **--to-nbdays** *\<number of days\>*

  The --to-nbdays CLI option can be used to determine the number of notifications that would be sent in a given timeframe.

  If **--from-nbdays** is not specified, ipa-epn will look within a 24-hour long time range in \<number of days\> days.

  if **--from-nbdays** is specified, the date range starts at **--from-nbdays** days in the future and ends at **--to-nbdays** in the future.

  Together, these two CLI options can be used to determine how many emails would be sent in a specific time in the future.

  The **--to-nbdays** CLI option implies **--dry-run**.

- **--from-nbdays** *\<number of days\>*

  See **--to-nbdays** for an explanation. This option must be used in conjunction with **--to-nbdays**.

- **--dry-run**

  The **--dry-run** CLI option is intended to test ipa-epn's configuration.

  For instance, if notify\_ttls is set to 21, 14, 3, **--dry-run** would display the list of users whose passwords would expire in 21, 14, and 3 days in the future.

- **--mail-test**

  The **--mail-test** CLI option will send an e-mail to the configured smtp\_admin value in /etc/ipa/epn.conf. Generic values for the substitution variables are set so this is also useful for testing and configuring the mail template.

## TEMPLATE

The template for the e-mail message is contained in /etc/ipa/epn/expire\_msg.template. The following template variables are available.

- User ID: uid

  - Full name: fullname

  - First name: first

  - Last name: Last

  - Password expiration date: expiration
