(2016-05-09) Notifying Users By E-mail Their Password Is Going To Expire (Update 5)

Posted by Jorge on 2016-05-09


Around 2009 I wrote a blog post about and also wrote a tool to notify users through e-mail when their password was going to expire. You can read all the details about the idea here. Now that tool was very inflexible and because of that I received numerous requests to make it more flexible such as the ability to customize the e-mail message. With this blog post I’m sharing a brand new tool, based upon PowerShell, that will notify users through e-mail when their password is going to expire. So let’s get started in explaining on this works! I did not test all combinations! However, I do expect it to run on any Windows version as long as PowerShell is available. It should also work against any AD version and there is NO dependency on using the AD PowerShell CMDlets!. Everything is done through ADSI to be independent of Windows versions! It will also support PSOs if the DFL is high enough and PSOs are configured!

SYNTAX:

  • <PoSH Script File> –> Runs The Script In Test Mode While NOT Sending Any E-Mails
  • <PoSH Script File> -force:$true –> Runs The Script In DEV (One Mail To Configured Admin) Or TEST (All Mails To Configured Admin) Or PROD (Mails To Users) Mode While Sending Any E-Mails

Please provide feedback through the comments section OR you the contact page

DISCLAIMER (READ THIS!):

  • I wrote this script, therefore I own it. Anyone asking money for it, should NOT be doing that and is basically ripping you off!
  • The script is freeware, you are free to use it and distribute it, but always refer to this website (https://jorgequestforknowledge.wordpress.com/) as the location where you got it.
  • This script is furnished "AS IS". No warranty is expressed or implied!
  • I have NOT tested it in every scenario nor have I tested it against every Windows and/or AD version
  • Always test first in lab environment to see if it meets your needs!
  • Use this script at your own risk!
  • I do not warrant this script to be fit for any purpose, use or environment!
  • I have tried to check everything that needed to be checked, but I do not guarantee the script does not have bugs!
  • I do not guarantee the script will not damage or destroy your system(s), environment or whatever!
  • I do not accept liability in any way if you screw up, use the script wrong or in any other way where damage is caused to your environment/systems!
  • If you do not accept these terms do not use the script in any way and delete it immediately!

REMARKS (READ THIS!):

  • The script requires PowerShell v2.0 at a minimum
  • This script must be able to read the contents of the PSO container in every AD domain the script will target!. By default only Domain Admins can read this.
  • It is therefore needed to delegate those permissions to the account executing this PoSH script.
  • For more information about this see the blog post: https://jorgequestforknowledge.wordpress.com/2007/08/09/windows-server-2008-fine-grained-password-policies/
  • DSACLS "\\<Some RWDC>\CN=Password Settings Container,CN=System,<Your AD domain DN>" /G "<Some Security Principal>:GR" /I:T
    • This assign <Some Security Principal> with Allow:Read on the Password Settings Container including its descendant objects

The tool uses an XML called "AD-Pwd-Exp-Notify.xml". It is pre-filled with examples from my test/demo environment. Make sure to change as needed to accommodate your own environment and requirements!

The script has four execution modes. When NOT running the PowerShell script with the ‘-force’ parameter, it will by default run in TEST mode without sending any e-mail to users regarding password expiry ("TEST (NO MAILINGS)"), no matter what the configuration in the XML files specifies. When running the PowerShell script with the ‘-force’ parameter, it will look in the XML file to see which execution mode to run in. When "DEV" is specified it will only send 1 mail to the SMTP address of the admin user specified in the "toSMTPAddressInTestMode" configuration field. This mode allows you to develop the solution being swamped in e-mails or impacting your users. When "TEST" is specified it will only send all mails to the SMTP address of the admin user specified in the "toSMTPAddressInTestMode" configuration field. This mode allows you to see/experience what your scoped/targeted users would see/experience without actually impacting them. When "PROD" is specified it will only send all mails to the SMTP address of the individual users. This really sends the e-mails to all the scoped/targeted individual users.

<!– Execution Mode: DEV (1 Mail To Admin User) or TEST (All Mails To Admin User) or PROD (All Mails To Individual Users) –>

<executionMode>DEV</executionMode>

The PowerShell script sends e-mail, therefore it requires a FROM e-mail address

<!– The SMTP Address Used In The FROM Field –>

<mailFromSender>general.DO-NOT-REPLY@iamtec.nl</mailFromSender>

To develop the solution and test it you can specify an SMTP address that will be used to send e-mails to, without impacting the real user community. That SMTP address will also be used for notifications is the SMTP server or DC is unavailable.

<!– The SMTP Address Used When Running In DEV/TEST Mode And Also Used For Notifications –>

<toSMTPAddressInTestMode>adm.root@iamtec.nl</toSMTPAddressInTestMode>

The PowerShell script sends e-mail, therefore it requires an SMTP server. A test connection to the SMTP server is made. If it fails the script aborts!

<!– FQDN Of The Mail Server Or Mail Relay –>

<smtpServer>MAIL.IAMTEC.NET</smtpServer>

The priority of the mail send can be configured as Low, Normal or High

<!– The Priority Of The Message: Low, Normal, High –>

<mailPriority>High</mailPriority>

The script supports multi-lingual messages. You must always specify a default language and for each language you must also specify a mail subject and the full path to HTML body file that contains the text in a specific language. Both the subject and the body support variables that can be replaced by the actual values. The script contains an example for US (English) and the same example for NL (Dutch).

<!– The File With The HTML Body Text For A Specific Language And The Subject. Supported Variables: FIRST_NAME, LAST_NAME, DISPLAY_NAME, FQDN_DOMAIN, PWD_EXPIRE_IN_NUM_DAYS, PWD_EXPIRY_DATE, PWD_MIN_LENGTH, PWD_MIN_AGE, PWD_MAX_AGE, PWD_HISTORY, PWD_COMPLEX, PWD_CHANGE_RESET_URL  –>
<htmlBodyFiles>
    <htmlBodyFile language="default" mailSubject="Expiring Password In Approx. PWD_EXPIRE_IN_NUM_DAYS Days – Change Your Password As Soon As Possible!" fullPath="D:\TEMP\ADPwdExpNotifyMessageBody_US.html" />
    <htmlBodyFile language="US" mailSubject="Expiring Password In Approx. PWD_EXPIRE_IN_NUM_DAYS Days – Change Your Password As Soon As Possible!" fullPath="D:\TEMP\ADPwdExpNotifyMessageBody_US.html" />
    <htmlBodyFile language="NL" mailSubject="Verlopen Wachtwoord In Ongeveer PWD_EXPIRE_IN_NUM_DAYS Dagen – Wijzig Uw Wachtwoord Zo Snel Als Mogelijk!" fullPath="D:\TEMP\ADPwdExpNotifyMessageBody_NL.html" />
</htmlBodyFiles>

If you have a web portal (e.g. FIM SSPR or Exchange Change Password) to change and/or reset the password, then you can specify it here

<!– The URL Where The Users Can Change Or Reset Their Password –>

<pwdChangeOrResetURL>https://ssprportal.iamtec.net:447/</pwdChangeOrResetURL>

Logging to screen can be enabled (ON) or disabled (OFF).

<!– Enable/Disable Logging To Screen: ON or OFF –>

<logToScreen>ON</logToScreen>

Logging tofile can be enabled (ON) or disabled (OFF).

<!– Enable/Disable Logging To A Log File: ON or OFF –>

<logToFile>ON</logToFile>

If logging is enabled, then you must specify the full path to the log file that will be used. The script itself will take date and time into account

<!– Full Path Of The Log File (.LOG Extension!) –>

<fullPathToLogFile>D:\TEMP\ADPwdExpNotify.log</fullPathToLogFile>

To make sure the disk is not swamped with a huge number of log files, you can specify for how many days the script will keep log files. Every log file older than the specified number will be deleted

<!– Number Of Days To Keep LOG Files –>

<numDaysLOGToKeep>30</numDaysLOGToKeep>

When enabled (ON), the script will export the information of users to a CSV file for troubleshooting and analyses. When disabled (OFF) nothing is exported.

<!– Enable/Disable Export Of Notified Accounts To A CSV File: ON or OFF –>

<exportToCSV>ON</exportToCSV>

If exporting is enabled, then you must specify the full path to the CSV file that will be used. The script itself will take date and time into account

<!– Full Path Of The CSV File (.CSV Extension!) –>

<fullPathToCSVFile>D:\TEMP\ADPwdExpNotify.csv</fullPathToCSVFile>

To make sure the disk is not swamped with a huge number of CSV files, you can specify for how many days the script will keep CSV files. Every CSV file older than the specified number will be deleted

<!– Number Of Days To Keep CSV Files –>

<numDaysCSVToKeep>30</numDaysCSVToKeep>

In the XML config file you can specify the date/time format to be used on screen, in the log, in the CSV and in the E-mail message

<!– Date And Time Format To Use On Screen, In Logs And In E-mail Message –>
<formatDateTime>yyyy-MM-dd HH:mm:ss</formatDateTime>

In this section you specify every AD domain in the AD forest, including trusting AD domains, for which its scoped/targeted users must be notified. For every AD domain, you then need to specify if an RWDC needs to be discovered (specifiy: DISCOVER) or you can specifically mention an RWDC that must be targeted. A test connection to the RWDC is made. If it fails the AD domain for that RWDC is fully skipped! Then for every AD domain, specify one or more search bases to scope/target users in the LDAP query. For every search base configure the language for the scoped/targeted users. Make sure that if you specify specific languages, that you also have configured the HTML Body File for that language

<!– Targeted Domains, Specify DISCOVER To Discover A DC Or Use Specific DC And Search Bases Per Domain –>
<!– WARNING: Make Sure The Search Bases DO NOT Overlap Each Other!!! –>
<domains>
    <domain FQDN="IAMTEC.NET" DC="DISCOVER">
        <searchBase nr="1" language="default">OU=Users,OU=EMPLOYEES,OU=Org-Users,DC=IAMTEC,DC=NET</searchBase>

        <searchBase nr="5" language="NL">OU=Users,OU=HISTORY2,OU=Org-Users,DC=CHILD,DC=IAMTEC,DC=NET</searchBase>
    </domain>
</domains>

In this section you can specify one or multiple periods of notifications. Make sure that none of the periods overlaps any other period!. In the example shown, the scoped/targeted user will receive 4 notifications assuming the script executes once every day. Also make sure the periods configured are in balance with the maximum password age!

<!– Number Of Days Before The Password Expires To Send Notifications –>
<!– WARNING: Make Sure The Periods DO NOT Overlap Each Other!!! –>
<daysBeforeWarn>
    <period nr="1" Max="10" Min="9" />
    <period nr="2" Max="5" Min="4" />
    <period nr="3" Max="2" Min="0" />
</daysBeforeWarn>
