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.

.Sh DESCRIPTION
|
|
.Nm
|
|
is used to authenticate to the Kerberos server as
|
|
.Ar principal ,
|
|
or if none is given, a system generated default (typically your login
|
|
name at the default realm), and acquire a ticket granting ticket that
|
|
can later be used to obtain tickets for other services.
|
|
.Pp
|
|
Supported options:
|
|
.Bl -tag -width Ds
|
|
.It Fl c Ar cachename Fl Fl cache= Ns Ar cachename
|
|
The credentials cache to put the acquired ticket in, if other than
|
|
default.
|
|
.It Fl f Fl Fl no-forwardable
|
|
Get ticket that can be forwarded to another host, or if the negative
|
|
flags use, don't get a forwardable flag.
|
|
.It Fl t Ar keytabname , Fl Fl keytab= Ns Ar keytabname
|
|
Don't ask for a password, but instead get the key from the specified
|
|
keytab.
|
|
.It Fl l Ar time , Fl Fl lifetime= Ns Ar time
|
|
Specifies the lifetime of the ticket.
|
|
The argument can either be in seconds, or a more human readable string
|
|
like
|
|
.Sq 1h .
|
|
.It Fl p , Fl Fl proxiable
|
|
Request tickets with the proxiable flag set.
|
|
.It Fl R , Fl Fl renew
|
|
Try to renew ticket.
|
|
The ticket must have the
|
|
.Sq renewable
|
|
flag set, and must not be expired.
|
|
.It Fl Fl renewable
|
|
The same as
|
|
.Fl Fl renewable-life ,
|
|
with an infinite time.
|
|
.It Fl r Ar time , Fl Fl renewable-life= Ns Ar time
|
|
The max renewable ticket life.
|
|
.It Fl S Ar principal , Fl Fl server= Ns Ar principal
|
|
Get a ticket for a service other than krbtgt/LOCAL.REALM.
|
|
.It Fl s Ar time , Fl Fl start-time= Ns Ar time
|
|
Obtain a ticket that starts to be valid
|
|
.Ar time
|
|
(which can really be a generic time specification, like
|
|
.Sq 1h )
|
|
seconds into the future.
|
|
.It Fl k , Fl Fl use-keytab
|
|
The same as
|
|
.Fl Fl keytab ,
|
|
but with the default keytab name (normally
|
|
.Ar FILE:/etc/krb5.keytab ) .
|
|
.It Fl v , Fl Fl validate
|
|
Try to validate an invalid ticket.
|
|
.It Fl e , Fl Fl enctypes= Ns Ar enctypes
|
|
Request tickets with this particular enctype.
|
|
.It Fl Fl password-file= Ns Ar filename
|
|
read the password from the first line of
|
|
.Ar filename .
|
|
If the
|
|
.Ar filename
|
|
is
|
|
.Ar STDIN ,
|
|
the password will be read from the standard input.
|
|
.It Fl Fl fcache-version= Ns Ar version-number
|
|
Create a credentials cache of version
|
|
.Ar version-number .
|
|
.It Fl a , Fl Fl extra-addresses= Ns Ar enctypes
|
|
Adds a set of addresses that will, in addition to the systems local
|
|
addresses, be put in the ticket.
|
|
This can be useful if all addresses a client can use can't be
|
|
automatically figured out.
|
|
One such example is if the client is behind a firewall.
|
|
Also settable via
|
|
.Li libdefaults/extra_addresses
|
|
in
|
|
.Xr krb5.conf 5 .
|
|
.It Fl A , Fl Fl no-addresses
|
|
Request a ticket with no addresses.
|
|
.It Fl Fl anonymous
|
|
Request an anonymous ticket (which means that the ticket will be
|
|
issued to an anonymous principal, typically
|
|
.Dq anonymous@REALM ) .
|
|
.It Fl Fl enterprise
|
|
Parse principal as a enterprise (KRB5-NT-ENTERPRISE) name. Enterprise
|
|
names are email like principals that are stored in the name part of
|
|
the principal, and since there are two @ characters the parser needs
|
|
to know that the first is not a realm.
|
|
An example of an enterprise name is
|
|
.Dq lha@e.kth.se@KTH.SE ,
|
|
and this option is usually used with canonicalize so that the
|
|
principal returned from the KDC will typically be the real principal
|
|
name.
|
|
.It Fl Fl afslog
|
|
Gets AFS tickets, converts them to version 4 format, and stores them
|
|
in the kernel.
|
|
Only useful if you have AFS.
|
|
.El
|
|
.Pp
|
|
The
|
|
.Ar forwardable ,
|
|
.Ar proxiable ,
|
|
.Ar ticket_life ,
|
|
and
|
|
.Ar renewable_life
|
|
options can be set to a default value from the
|
|
.Dv appdefaults
|
|
section in krb5.conf, see
|
|
.Xr krb5_appdefault 3 .
|
|
.Pp
|
|
If a
|
|
.Ar command
|
|
is given,
|
|
.Nm
|
|
will set up new credentials caches, and AFS PAG, and then run the given
|
|
command.
|
|
When it finishes the credentials will be removed.
|
|
.Sh ENVIRONMENT
|
|
.Bl -tag -width Ds
|
|
.It Ev KRB5CCNAME
|
|
Specifies the default credentials cache.
|
|
.It Ev KRB5_CONFIG
|
|
The file name of
|
|
.Pa krb5.conf ,
|
|
the default being

|
