.SH "NAME"
|
|
ipa\-rmkeytab \- Remove a kerberos principal from a keytab
|
|
.SH "SYNOPSIS"
|
|
ipa\-rmkeytab [ \fB\-p\fR principal\-name ] [ \fB\-k\fR keytab\-file ] [ \fB\-r\fR realm ] [ \fB\-d\fR ]
|
|
|
|
.SH "DESCRIPTION"
|
|
Removes a kerberos principal from a \fIkeytab\fR.
|
|
|
|
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.
|
|
|
|
\fBNOTE:\fR 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.
|
|
.SH "OPTIONS"
|
|
.TP
|
|
\fB\-p principal\-name\fR
|
|
The non\-realm part of the full principal name.
|
|
.TP
|
|
\fB\-k keytab\-file\fR
|
|
The keytab file to append the principal(s) from.
|
|
.TP
|
|
\fB\-r realm\fR
|
|
A realm to remove all principals for.
|
|
.TP
|
|
\fB\-d\fR
|
|

.SH "EXAMPLES"

|
|
|
|
