NAME

ipa-rmkeytab - Remove a kerberos principal from a keytab

SYNOPSIS

ipa-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 principal 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 remove 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
