Examples

The following example shows the membership Element (ASP.NET Settings Schema) configuration element in the system.web section of the application's Web.config file. It specifies that the application use an instance of the ActiveDirectoryMembershipProvider class to provide membership services and sets the passwordStrengthRegularExpression attribute to a regular expression that validates that the password meets the following criteria:

  • Is greater than seven characters.

If the password does not meet these criteria, the password is not accepted by the membership provider.
