several new kerberos related libraries and applications to FreeBSD:
o kgetcred(1) allows one to manually get a ticket for a particular service.
o kf(1) securily forwards ticket to another host through an authenticated
and encrypted stream.
o kcc(1) is an umbrella program around klist(1), kswitch(1), kgetcred(1)
and other user kerberos operations. klist and kswitch are just symlinks
to kcc(1) now.
o kswitch(1) allows you to easily switch between kerberos credentials if
you're running KCM.
o hxtool(1) is a certificate management tool to use with PKINIT.
o string2key(1) maps a password into key.
o kdigest(8) is a userland tool to access the KDC's digest interface.
o kimpersonate(8) creates a "fake" ticket for a service.
We also now install manpages for some lirbaries that were not installed
before, libheimntlm and libhx509.
- The new HEIMDAL version no longer supports Kerberos 4. All users are
recommended to switch to Kerberos 5.
- Weak ciphers are now disabled by default. To enable DES support (used
by telnet(8)), use "allow_weak_crypto" option in krb5.conf.
- libtelnet, pam_ksu and pam_krb5 are now compiled with error on warnings
disabled due to the function they use (krb5_get_err_text(3)) being
deprecated. I plan to work on this next.
- Heimdal's KDC now require sqlite to operate. We use the bundled version
and install it as libheimsqlite. If some other FreeBSD components will
require it in the future we can rename it to libbsdsqlite and use for these
components as well.
- This is not a latest Heimdal version, the new one was released while I was
working on the update. I will update it to 1.5.2 soon, as it fixes some
important bugs and security issues.

|
Verbose output.
|
|

can be one of the following:
|
|

|
|
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 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 copy Ar keytab-src Ar keytab-dest
|
|
Copies all the entries from
|
|
.Ar keytab-src
|
|
to
|
|
.Ar keytab-dest .
|
|
.It get Oo Fl p Ar admin principal Oc \
|
|
Oo Fl Fl principal= Ns Ar admin principal Oc Oo Fl e Ar enctype Oc \
|
|
Oo Fl Fl enctypes= Ns Ar enctype Oc Oo Fl r Ar realm Oc \

|
|
Oo Fl Fl admin-server= Ns Ar admin server Oc Oo Fl s Ar server port Oc \
|
|
Oo Fl Fl server-port= Ns Ar server port Oc Ar principal ...
|
|
For each
|
|
.Ar principal ,
|
|
generate a new key for it (creating it if it doesn't already exist),
|
|
and put that key in the keytab.
|
|
.Pp
|
|
If no
|
|
.Ar realm
|
|
is specified, the realm to operate on is taken from the first
|
|
principal.
|
|
.It list Oo Fl Fl keys Oc Op Fl Fl timestamp
|
|
List the keys stored in the keytab.
|
|
.It remove Oo Fl p Ar principal Oc Oo Fl Fl principal= Ns Ar principal Oc \
|
|

|
|
Oo Fl Fl enctype= Ns Ar enctype Oc
|
|

|
|
.Ar kvno
|
|
removes keys with any version number. Not specifying an
|
|
.Ar enctype
|
|

|
|
.It rename Ar from-principal Ar to-principal
|
|
Renames all entries in the keytab that match the
|
|
.Ar from-principal
|
|
to
|
|
.Ar to-principal .
|
|
.It 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
|
|
