Hello Team,
I'm currently dealing with an issue where UIA is unable to validate certification.
The certificate does not have a SAN setting.
I plan to change the certificate to one that has both CN and SAN set, but have not been able to do so yet.
The certificate validation has occurred since applying an OS patch, so I have asked the OS vendor to investigate.
The OS vendor has stated that there is no Schannel SSP communication when the issue occurs.
The OS vendor has asked me to confirm whether UIA uses Schannel SSP.
Does anyone have information on whether UIA uses Schannel SSP for SSL/TLS communication?
Regards,
Yusuke Narita
