.SH "NAME"
|
||
|
|
ipa\-getkeytab \- Get a keytab for a kerberos principal
|
||
|
|
.SH "SYNOPSIS"
|
||
|
|
ipa\-getkeytab [\fI-a\fR] \fIprincipal-name\fR \fIfile-name\fR
|
||
|
|
|
||
|
|
.SH "DESCRIPTION"
|
||
|
|
Retrieves a kerberos \fIkeytab\fR and optionally adds a
|
||
|
|
service \fIprincipal\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. For example, the following
|
||
|
|
is an example principal for an ldap server:
|
||
|
|
|
||
|
|
ldap/foo.example.com@EXAMPLE.COM
|
||
|
|
|
||
|
|
When using ipa-getkeytab the realm name is already
|
||
|
|
provided, so the principal name is just the service
|
||
|
|
name and hostname (ldap/foo.example.com from the
|
||
|
|
example above).
|
||
|
|
|
||
|
|
\fBWARNING:\fR retrieving the keytab resets the secret
|
||
|
|
rendering all other keytabs for that principal invalid.
|
||
|
|
|
||
|
|
.SH "OPTIONS"
|
||
|
|
.TP
|
||
|
|
\fB\-a\fR
|
||
|
|
Add the service principal in addition to getting the keytab
|
||
|
|
|
||
|
|
.SH "EXAMPLES"
|
||
|
|
|
||
|
|
Add and retrieve a keytab for the ldap service principal on
|
||
|
|
the host foo.example.com and save it in the file ldap.keytab.
|
||
|
|
|
||
|
|
# ipa-getkeytab -a ldap/foo.example.com ldap.keytab
|
||
|
|
|
||
|
|
.SH "EXIT STATUS"
|
||
|
|
The exit status is 0 on success, nonzero on error.
