In build 90, the kclient script was enhanced. The script includes the feature of joining Microsoft Active Directory servers. See How to Interactively Configure a Kerberos Client and How to Configure a Kerberos Client for an Active Directory Server for instructions. In addition, the script includes a -T option that may be used to identify the KDC server type for the client. All of the options for this script are covered in the kclient(1M) man page.
In build 102, the /etc/krb5/kadm5.keytab file is no longer needed. The keys that were stored in this file are now directly read from the Kerberos database.
