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
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.

Description |
Beginning characters of a dictionary word |
Specify number of characters in the password to match with the beginning of a word in dictionary before rejecting it. The characters in the password must be more than the specified number, for this option to work efficiently. |
A complete word from the dictionary (QPMDictionary.txt) |
Select this check box to reject passwords that represent an entire word stored in the dictionary. |
Detect inclusion of non-alpha characters (pas7swo%rd) |
Select this check box to remove non-alphabetic characters during analysis. |
Enable bi-directional analysis |
Select to reject passwords containing an entire dictionary word or its part (depending on which of the other three options you have selected), if read backwards. |

NOTE: Password Policy Manager installation is not necessary, if Password Manager is installed on Domain Controller, and user wants to enable only dictionary rule. |
The symmetry rule ensures that password or its part does not read the same in both directions.
For example, if you enable the Reject passwords that read the same in both directions option, then the password “redivider” will be rejected.
To configure the symmetry rule

Reject passwords that read the same in both directions (pass8ssap) |

Maximum number of beginning characters that match ending characters of password if read backwards (pas47sap) |
Specify the number of beginning characters matching the ending characters of password, if read backwards, which the policy will tolerate before rejecting a password. |
Maximum number of consecutive characters within a password, that read the same in both directions (pass4554word) |
Specify the number of password characters in a row that read the same in both directions, which the policy will tolerate before rejecting a password. |

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.
