When Offline Password Reset is enabled in the Forgot Password workflow and the challenge code is entered the following error is displayed:
"The specified directory service attribute or value does not exist"
This error results from the Offline Password setting not being configured in the GPO on the Domain Controllers (DCs). This issue will persist until the configurations are enabled in the GPO on the DCs. Please find attached a screen shot for your reference.
The Password Manager Admin guide also covers the Offline Password reset configuration on page 95. All of these configurations must be in place and complete for the product to function.
