How to force sudo to use existing kerberos ticket?

Ok, so I'm using Windows Server 2012 as a Domain Controller. I've connected two Centos7 clients to the domain via samba.

Authentication works as expected via SSH; however, when attempting to sudo, pam still asks for a password.

Once you supply the appropriate password, everything works fine, but I'm looking for a method that would avoid the previously mentioned password request.

I've been playing around with PAM, but haven't had too much luck.

/etc/pam.d/sudo:

#%PAM-1.0
#auth       include      system-auth
auth       required     pam_sss.so
account    include      system-auth
password   include      system-auth
session    optional     pam_keyinit.so revoke
session    required     pam_limits.so

/etc/pam.d/system-auth:

#%PAM-1.0
# This file is auto-generated.
# User changes will be destroyed the next time authconfig is run.
