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.
