Jay, did you have to put in the hostname of the dc that actually performs the Kerberos auth? I am wondering if I need to specify this in the command or the krb5.conf file ...It is not working for me. I am using MYDOMAINNAME.COM as the AD domain name with and without brackets around it. Time is synced to dc. Thanks, Isaac
