Configure Regular Expression Matching

You configure regular expressions to specify text patterns that are used for string matching. A password must match or not match the expression to be valid. Each regular expression entry is a name/value pair consisting of a descriptive tag and expression definition.

Regular expression matching for passwords is optional. If you decide to use regular expression, you only specify entries for expressions that passwords must match or must not match. If you have no expression matching requirements, do not create any regular expression entries.

To configure regular expressions for passwords

1. In the Password Policy dialog, select the Regular Expressions tab.

   You will see an empty table in the Regular Expressions group box.

2. Click Add to add an expression.

   The Password Regular Expression dialog opens.

3. Select one of the following radio buttons:
   • MUST Match

     If you select this option, define a regular expression that passwords must match.

   • MUST NOT Match

     If you select this option, add an entry for each regular expression that passwords must not match.

4. Enter values for the fields.

   Note: Click Help for descriptions of settings and controls, including their respective requirements and limits.

5. Click OK.

   The regular expression is added to the table. If you selected MUST NOT match, you will see a checkbox in the NO Match column.
