Steps to reproduce the problem:
Our Enterprise environment , Proxy user authentication happened Kerberos method(silent logon) through Microsoft Active Directory. After chrome update to latest version 69.0.3497.81, Kerberos user authentication is failed, due to this user prompting for username and password. Deployment of active directory in our environment  has different subdomains domain(CORP.AD.XX,PAT.AD.XX,CHE.AD.XX,KEL.AD.XX..)hence, we configure only proxy server domain name(wg-itnw-mum) proxy servers address in browser LAN settings instead of FQDN(wg-itnw-mum.corp.ad.xx). Proxy server name resolve depend on sub domain where it resolve. Latest chrome version Kerberos user authentication is Success when we configure FQDN(wg-itnw-mum.corp.ad.xx) but it failed when configure domain name alone(wg-itnw-mum). However, Same setting working well with IE, Firefox and even previous version of chrome. 

What is the expected behavior?
successful logon (silent logon)

What went wrong?
