Allow Kerberos Authentication
NTLM authentication method is not secure anymore, Microsoft disables it by a security update. Is there any chance the application can support Kerberos instead of NTLM?

NTLM like make many other authentication systems are often susceptible to information disclosure or replay attacks. This is not new information. Choosing one authentication system over another is not a substitute for appropriate hardening of your systems. Mitigation details can be found in the following KB linked form he page you provided https://support.microsoft.com/en-gb/topic/kb5005413-mitigating-ntlm-relay-attacks-on-active-directory-certificate-services-ad-cs-3612b773-4043-4aa9-b23d-b87910cd3429
That said, I'm a fan of kerberos and I'll look in to integrating it. Thanks for the suggestion.
Thanks for the update! The security decisions within the company are not made by me, and I'm not the one who manages the AD CA. I just need to leave with it as a DevOps engineer who does not want to generate SSL certificates manually. I appreciate your hard work and dedication to support this project!
