Log outputs differ depending on the version of the integrated Windows authentication module you are using.
For the integrated Windows authentication module version 8.0.0, it is not possible to output a log when the authentication fails since it is performed by IIS.
For the integrated Windows authentication module version 8.0.1. or later, a log is output at the Warning level when the authentication fail.
If you cannot log in to the iAP due to reasons such as absence of users in the iAP although the integrated Windows authentication was successful, a log is not output to the security log in any version. It is not possible to output a log by changing the settings, etc.
