.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 Xo
.Fl c Ar cachename
.Fl -cache= Ns Ar cachename
.Xc
The credentials cache to put the acquired ticket in, if other than
default.
.It Xo
.Fl canonicalize
.Xc
ask the KDC canonicalize the client name and server name. Useful with
enterprise names, PK-INIT, and LKDC realms when the user doesn't know
its real kerberos user name.
.It Xo
.Fl f ,
.Fl -forwardable
.Xc
Get ticket that can be forwarded to another host.
.It Xo
.Fl t Ar keytabname ,
.Fl -keytab= Ns Ar keytabname
.Xc
Don't ask for a password, but instead get the key from the specified
keytab.
.It Xo
.Fl l Ar time ,
.Fl -lifetime= Ns Ar time
.Xc
Specifies the lifetime of the ticket.
The argument can either be in seconds, or a more human readable string
like
.Sq 1h .
.It Xo
.Fl p ,
.Fl -proxiable
.Xc
Request tickets with the proxiable flag set.
.It Xo
.Fl R ,
.Fl -renew
.Xc
Try to renew ticket.
The ticket must have the
.Sq renewable
flag set, and must not be expired.
.It Fl -renewable
The same as
.Fl -renewable-life ,
with an infinite time.
.It Xo
.Fl r Ar time ,
.Fl -renewable-life= Ns Ar time
.Xc
The max renewable ticket life.
.It Xo
.Fl S Ar principal ,
.Fl -server= Ns Ar principal
.Xc
Get a ticket for a service other than krbtgt/LOCAL.REALM.
.It Xo
.Fl s Ar time ,
.Fl -start-time= Ns Ar time
.Xc
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 Xo
.Fl k ,
.Fl -use-keytab
.Xc
The same as
.Fl -keytab ,
but with the default keytab name (normally
.Ar FILE:/etc/krb5.keytab ) .
.It Xo
.Fl v ,
.Fl -validate
.Xc
Try to validate an invalid ticket.
.It Xo
.Fl e ,
.Fl -enctypes= Ns Ar enctypes
.Xc
Request tickets with this particular enctype.
.It Xo
.Fl -password-file= Ns Ar filename
.Xc
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 Xo
.Fl -fcache-version= Ns Ar version-number
.Xc
Create a credentials cache of version
.Ar version-number .
.It Xo
.Fl -extra-addresses= Ns Ar addresses
.Xc
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 Xo
.Fl a
.Xc
request tickets with addresses.
.It Xo
.Fl A ,
.Fl -no-addresses
.Xc
Request a ticket with no addresses.
.It Xo
.Fl -anonymous
.Xc
Request an anonymous ticket (which means that the ticket will be
issued to an anonymous principal, typically
.Dq anonymous@REALM ) .
.It Xo
.Fl V ,
.Fl -verbose
.Xc
Print slightly more verbose output from kinit when successful.
.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
.Pa /etc/krb5.conf .
.It Ev KRBTKFILE
Specifies the Kerberos 4 ticket file to store version 4 tickets in.
