This commit won't compile on it's own, as we need to fix the build system to cope in the next commit. The purpose of this commit is to update to a new lorikeet-heimdal tree that includes the previous two patches and is rebased on a current Heimdal master snapshot.

|
|
Verbose output.
|
|

|
|
can be one of the following:
|
|
.Bl -tag -width srvconvert

Oo Fl Fl password= Ns Ar password Oc Oo Fl r Oc Oo Fl Fl random Oc \
|
|
Oo Fl s Oc Oo Fl Fl no-salt Oc Oo Fl H Oc Op Fl Fl hex
|
|
Adds a key to the keytab. Options that are not specified will be
|
|
prompted for. This requires that you know the password or the hex key of the
|
|
principal to add; if what you really want is to add a new principal to
|
|
the keytab, you should consider the
|
|
.Ar get
|
|
command, which talks to the kadmin server.
|
|
.It Nm change Oo Fl r Ar realm Oc Oo Fl Fl realm= Ns Ar realm Oc \
|
|

|
Oo Fl Fl a Ar host Oc Oo Fl Fl admin-server= Ns Ar host Oc \
|
|
Oo Fl Fl s Ar port Oc Op Fl Fl server-port= Ns Ar port
|
|
Update one or several keys to new versions. By default, use the admin
|
|
server for the realm of a keytab entry. Otherwise it will use the
|
|
values specified by the options.
|
|
.Pp
|
|
If no principals are given, all the ones in the keytab are updated.
|
|
.It Nm copy Oo Fl Fl copy-duplicates Oc Ar keytab-src Ar keytab-dest
|
|
Copies all the entries from
|
|
.Ar keytab-src
|
|
to
|
|
.Ar keytab-dest .
|
|
Because entries already in
|
|
.Ar keytab-dest
|
|
are kept, this command functions to merge keytabs.
|
|
Entries for the same principal, key version number, and
|
|
encryption type in the
|
|
.Ar keytab-src
|
|
that are also in the
|
|
.Ar keytab-dest
|
|
will not be copied to the
|
|
.Ar keytab-dest
|
|
unless the
|
|
.Fl Fl copy-duplicates
|
|
option is given.
|
|
.It Nm get Oo Fl p Ar admin principal Oc \
|
|

|
|
.Pp
|
|
For each
|
|
.Ar principal ,
|
|
get a the principal's keys from the KDC via the kadmin protocol,
|
|
creating the principal if it doesn't exist (unless
|
|
.Fl Fl no-create
|
|
is given), and changing its keys to new random keys (unless
|
|
.Fl Fl no-change-keys
|
|
is given).
|
|
.Pp
|
|
If no
|
|
.Ar realm
|
|
is specified, the realm to operate on is taken from the first
|
|
principal.
|
|
.It Nm import Oo JSON-FILE Oc
|
|
Read an array of keytab entries in a JSON file and copy them to
|
|
the keytab.
|
|
Use the
|
|
.Nm list
|
|
command with its
|
|
.Fl Fl json
|
|
option
|
|
and
|
|
.Fl Fl keys

|
option to export a keytab.

|
|
.Nm import

|
|
Oo Fl V kvno Oc Oo Fl Fl kvno= Ns Ar kvno Oc Oo Fl e enctype Oc \
|
|
Oo Fl Fl enctype= Ns Ar enctype Oc

|
|

|
|
removes keys with any version number. Not specifying an
|
|
.Ar enctype
|
|
removes keys of any type.
|
|
.It Nm merge Oo Fl Fl copy-duplicates Oc Ar keytab-src Ar keytab-dest
|
|
An alias for the
|
|
.Nm copy
|
|
command.
|
|
.It Nm rename Ar from-principal Ar to-principal
|
|
Renames all entries for the
|
|
.Ar from-principal
|
|
in the keytab

|
to

|
|
.It Nm purge Op Fl Fl age= Ns Ar age
|

Removes all old versions of a key for which there is a newer version
|
|
that is at least

|
|
command has a
|
|
.Nm prune
|
|
command that can do this on the KDC side.
