Location where card range and enrollment verification errors are posted to.
This property is automatically filled whenever the DirectoryServerURL is set, as normally the EnrollmentErrorURL should be identical to the DirectoryServerURL. If it is required that errors be posted to a different address, this property can be changed before calling RequestCardRanges or VerifyEnrollment. Only errors generated by the RequestCardRanges and VerifyEnrollment methods will be posted to this URL. Errors generated by the CheckAuthenticationResponse method will be posted to the AuthenticationErrorURL. If this property is set to empty before calling the RequestCardRanges or VerifyEnrollment methods no errors will be posted.
