User Properties Rule
User Properties Rule
The user properties rule rejects passwords that contain part of a user account property value.
This rule splits the user account property value by non-alphanumeric characters (for example, “_”), and then checks if any part of the value is available in the password. For example, if user’s name is “Peter_US”, Password Manager splits the property into: “Peter” and “US”, and checks if any part can be found in the password. For example, the password “US_US” will be rejected.
To configure the user properties rule
- Follow the steps outlined in Configuring Password Policy Rules.
- On the Policy Rules tab, click User Properties Rule to expand the rule settings.
- Under User Properties Rule, select the Prevent users from using account properties as part of passwords check box, and then specify the following options:
Dictionary Rule
Dictionary Rule
The dictionary rule rejects passwords that match dictionary words or their parts.
The dictionary rule compares user passwords against a list of words stored in the QPMDictionary.txt text file (this file must use UTF-8 encoding). Depending on how you configure the rule settings, user passwords that partially or fully match dictionary words are rejected by Password Manager.
The QPMDictionary.txt (dictionary file) is located in the following folder: '\\<Domain Controller>\SYSVOL\<Domain>\31EB75A4-CD1A-4F67-94DA-9F8F5DF1F5C1', is deployed when user installs Password Policy Manager (PPM).
The dictionary file is never cached. During each password validity check, the dictionary file is read from the Password Manager server, or from the user's domain controller.
On the Policy Rules tab, click Dictionary Rule to expand the rule settings. Click Edit Dictionary File to edit or add new words to dictionary. After editing the file, click Save to save the changes. When user edits the dictionary file, the changes are saved in QPMDictionary.txt file which is in SYSVOL folder in Domain Controller. Service accounts must have access to this file from machines, where Password Manager is installed. When modifying the dictionary file, ensure that you begin every new word on a new line. It is recommended to maintain alphabetical order.
The dictionary rule is not case-sensitive which means that, on the one side, you can use either uppercase or lowercase when adding or modifying dictionary entries; and, on the other side, user input will undergo validity check irrespective of whether users use capitals or small letters in their passwords.
- To configure the dictionary rule
- Follow the steps outlined in Configuring Password Policy Rules.
- On the Policy Rules tab, click Dictionary Rule to expand the rule settings.
- Under Dictionary Rule, select the Enable dictionary lookup to reject passwords that contain check box. This enables administrators to control a set of rules using the Dictionary Rule feature. These rules can be modified as follows:

NOTE: Password Policy Manager installation is not necessary, if Password Manager is installed on Domain Controller, and user wants to enable only dictionary rule. |
Symmetry Rule
Symmetry Rule
The symmetry rule ensures that password or its part does not read the same in both directions.

Custom Rule
You can use this rule to create your own password policy message to be displayed on the Self-Service site when users change or reset their passwords. For example, if you want to hide all other policy messages and display your custom message to users, enable this policy rule, enter the message text, and select the Hide messages from other policy rules and display only this message check box. If you do not select this check box, messages from all enabled policy rules will be displayed.
Note, that this rule does not check the password compliance with the configured password policy. Configure this rule to display your custom message instead of or together with other policy messages when users change or reset passwords on the Self-Service site.
- To configure the custom rule
- Follow the steps outlined in Configuring Password Policy Rules.
- On the Policy Rules tab, click Custom Rule to expand the rule settings.
- Under Custom Rule, select the Enable check box to enable this rule.
- Select the Hide messages from other policy rules and display only this message check box if you want users to see only the custom password rule message and hide all other password policy messages.
- In the text box, enter the rule message in the default language (English). To enter the message in other languages, click the Add new language link, select the language, specify the message and click OK. Note, that only languages of the user interface of the Self-Service site are available in the list.
