Ever lost your password for the admin principle on your Linux Kerberos server? It is quite easy to recover by just setting a new one.
You just need to log in to your KDC and proceed as follows:
[root@ipa1 ~]# kadmin.local Authenticating as principal admin/admin@EXAMPLE.COM with password. kadmin.local: change_password admin@EXAMPLE.COM Enter password for principal "admin@EXAMPLE.COM": Re-enter password for principal "admin@EXAMPLE.COM": Password for "admin@EXAMPLE.COM" changed. kadmin.local: q [root@ipa1 ~]#
kinit to get a Kerberos ticket.
Have fun 🙂
