SYNOPSISipa-rmkeytab [ -p principal-name ] [ -k keytab-file ] [ -r realm ] [ -d
]
DESCRIPTION
Removes a kerberos principal from a keytab.
Kerberos keytabs are used for services (like sshd) to perform kerberos
authentication. A keytab is a file with one or more secrets (or keys)
for a kerberos principal.
A kerberos service principal is a kerberos identity that can be used
for authentication. Service principals contain the name of the service,
the hostname of the server, and the realm name.
ipa-rmkeytab provides two ways to remove principals. A specific prin‐
cipal can be removed or all principals for a given realm can be
removed.
All encryption types and versions of a principal are removed.
The realm may be included when removing a specific principal but it is
not required.
NOTE: removing a principal from the keytab does not affect the Kerberos
principal stored in the IPA server. It merely removes the entry from
the local keytab.
OPTIONS-p principal-name
The non-realm part of the full principal name.
-k keytab-file
The keytab file to append the principal(s) from.
-r realm
A realm to remove all principals for.
-d Debug mode. Additional information is displayed.
EXAMPLES
Remove the NFS service principal on the host foo.example.com from
/tmp/nfs.keytab.
# ipa-rmkeytab-p nfs/foo.example.com -k /tmp/nfs.keytab
Remove the ldap service principal on the host foo.example.com from
/etc/krb5.keytab.
# ipa-rmkeytab-p ldap/foo.example.com -k /etc/krb5.keytab
Remove all principals for the realm EXAMPLE.COM.
# ipa-rmkeytab-r EXAMPLE.COM -k /etc/krb5.keytab
