 This same tool is used to unconfigure IPA and attemps to return the machine to its previous state. Part of this process is to unenroll the host from the IPA server. Unenrollment consists of disabling the prinicipal key on the IPA server so that it may be re\-enrolled. The machine principal in /etc/krb5.keytab (host/<fqdn>@REALM) is used to authenticate to the IPA server to unenroll itself. If this principal does not exist then unenrollment will fail and an administrator will need to disable the host principal (ipa host\-disable <fqdn>).
