ActiveDirectoryMembershipProvider.RequiresQuestionAndAnswer Property
Assembly: System.Web (in system.web.dll)
Property Value
true if the ActiveDirectoryMembershipProvider object is configured to require a password question and answer for a user; otherwise, false. The default is false.The RequiresQuestionAndAnswer property is set in your application's configuration file using the requiresQuestionAndAnswer attribute of the membership Element (ASP.NET Settings Schema) element. If the property is not set in the application's configuration file, the RequiresQuestionAndAnswer property is set to the default value of false.
When the requiresQuestionAndAnswer attribute is set to true, you must also set these additional attributes.
-
attributeMapPasswordQuestion and attributeMapPasswordAnswer must be mapped to attributes in the Active Directory schema.
If the above criteria are not met, a ProviderException is thrown at initialization.
 Note |
|---|
| You can require a password question and answer when creating a user, but set the EnablePasswordReset property to false to prevent users from changing their passwords using the ActiveDirectoryMembershipProvider class. |
The following code example shows a Web.config entry that configures an ActiveDirectoryMembershipProvider instance to enable password resets. It uses the explicit credentials of a user given the "reset password" access right.
 Security Note |
|---|
| When you place user credentials in your Web.config file, there are potential security threats. Users with access rights to the directory containing the Web.config file can read the file, and thus see the credentials. For details on how to protect against this threat, see Encrypting Configuration Information Using Protected Configuration. |
