Introduction

The intent of this document to is record one method of enabling Kerberos logins on a CentOS 7 system using Windows Active Directory. There are many way to do this. For a very detailed document on all of these options, check out the Red Hat Enterprise Linux 7 Windows Integration Guide.

Note: At the time of this writing, a kickstart installation does not work correctly, possibly due to using an older version of adcli. The /etc/krb5.keytab file ends up containing entries that look like HOST/hostname.domain.com@DOMAIN.COM which is not what sshd is expecting. The sshd service is expecting entrieds that look like host/hostname.domain.com@DOMAIN.COM. This causes ssh Kerberos logins to fail, printing No key table entry found matching host/hostname.domain.com@ in the error log.
