Kerberos Keytab File Creation on Ubuntu

To create a kerberos keytab file on Ubuntu and with the kerberos packages installed (e.g. sudo apt-get install krb5-user )

root@jmcc02:~# ktutil
ktutil:  addent -password -p myusername@DOMAIN.TLD.COM -k 1 -e RC4-HMAC
Password for myusername@DOMAIN.TLD.COM:
ktutil:  wkt username.keytab
ktutil:  quit

After completing those steps there should be a keyfile created in the current directory. That keytab file can be used instead of using a password. For example:

/usr/bin/kinit myusername@DOMAIN.TLD.COM -k -t /root/username.keytab
