# System account maintainance commands

Within commands below, Don't take square brackets, angle brackets and triple-dots literally:

 * *< This >* should be replaced with your own info - including the angle brackets
 * *[This]* is optional parts of the command - including the square brackets
 * *...* means "repeat ad libitum" - leave it out or add more stuff similar to that right before the dots

## Normal users

### Create new account

 1. Pick a username:
  * Start with the initials of the user
  * Include also second letter of either first name or surname
  * If necessary, add third letter of first name or surname (or a trailing number)
  * The result should be practical (short and related to the name of the user) but must not be a nickname or initals: A username is comparable to the shape of a key - the user may get confused in every day use if it looks like a toy or jewelery!
 2. Create the account:

		localadduser <username> <fullname> <cellphone> [<otherphone>] <addresshint> [<addresshint>...]

  * Full name: Full name (Capital and small letters allowed, as is space and special characters, but no comma!)
  * Cellphone: Cellphone number including country code but without other spaces. Like this: +45 40843136
  * Addresshint: local part of email address, followed by @-sign, and optionally followed by mailgroup. Like these: jonas@ js@pool_of_maildomains
 3. Send an email based on [[intro/email.en]] skeleton:
  * If an ouside working email address has been provided, then use that as recipient. Alternatively use the contact person of the new user (teacher, boss etc.) as recipient.
  * Add \<username>@example.com as Cc:
  * Add hostmaster@example.com as Bcc:
  * Add teknik@lists.example.com as Reply-To:
 4. Send a cellphone text message based on [[intro/sms.en]], adding the the password spit out from the command above.

TODO: Automate more: sending out sms and email should happen automatically.

		(user=<username>; for group in <group1> [<group2> ...]; do adduser $user $group; done)

### Add/replace additional email addresses to account

	chfn <username>


## Update email address info in smtp server

 1. Run this command:

		localmaildomainprepare

 2. Check and correct warnings, and repeat above command.

 3. When satisfied with result, run this command:

		localmaildomainupdate

FIXME: localmaildomainupdate should email diff file to postmaster@example.com


## Extend password lifespan

If a user exceeds password lifespan, and still remembers the old password, the lifespan can be extended slightly to open a new window for changing it:

	localresetpasswdexpiry <username>

TODO: The above command should ideally emit an sms and/or email requesting the user to immediately change password

## Reset password

 1. Reset the actual password using the following command:

		localresetpasswd <username>

 2. Send a cellphone text message similar to the one for creating a new account.

TODO: The above command should ideally emit an sms and/or email rewuesting the user to immediately change password

## Warn about password expiry

 1. Notice log messages warning about passwords soon expiring
 2. Send a cellphone textmessage with the following content:

	    You must change your password - it soon expires! Read how and why at the web page http://support.redpill.dk/intro

    Or in danish:

	    Du skal ændre din adgangskode - den udløber snart! Læs hvordan og hvorfor på websiden http://support.redpill.dk/intro

TODO: Rewrite as automated syslog-ng plugin or cron script passing the message to an sms gateway.

### Locate users with short password lifespan

	(group=<gruppe>; echo $group:; for user in `members $group`; do chage -l $user|egrep -q '^Maximum:\[[:blank:]]*[0-9]{2}$' && printf $user'\t' && chage -l $user|egrep '^Password Expires:'; done)
