kinit
is used to authenticate to the Kerberos server as
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.
If you have compiled
kinit
with Kerberos 4 support and you have a
Kerberos 4 server,
kinit
will detect this and get you Kerberos 4 tickets.
Supported options:
-c cachename
--cache= cachename
The credentials cache to put the acquired ticket in, if other than
default.
-f
--forwardable
Get ticket that can be forwarded to another host.
-t keytabname
--keytab= keytabname
Don't ask for a password, but instead get the key from the specified
keytab.
-l time
--lifetime= time
Specifies the lifetime of the ticket. The argument can either be in
seconds, or a more human readable string like
`1h'
-p
--proxiable
Request tickets with the proxiable flag set.
-R
--renew
Try to renew ticket. The ticket must have the
`renewable'
flag set, and must not be expired.
--renewable
The same as
--renewable-life
with an infinite time.
-r time
--renewable-life= time
The max renewable ticket life.
-S principal
--server= principal
Get a ticket for a service other than krbtgt/LOCAL.REALM.
-s time
--start-time= time
Obtain a ticket that starts to be valid
time
(which can really be a generic time specification, like
`1h'
seconds into the future.
-k
--use-keytab
The same as
--keytab
but with the default keytab name (normally
FILE:/etc/krb5.keytab )
-v
--validate
Try to validate an invalid ticket.
-e
--enctypes= enctypes
Request tickets with this particular enctype.
--fcache-version= version
Create a credentials cache of version
version
-a
--extra-addresses= 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
libdefaults/extra_addresses
in
krb5.conf5.
--no-addresses
Request a ticket with no addresses.
--anonymous
Request an anonymous ticket (which means that the ticket will be
issued to an anonymous principal, typically
``anonymous@REALM )''
The following options are only available if
kinit
has been compiled with support for Kerberos 4.
-4
--524init
Try to convert the obtained Kerberos 5 krbtgt to a version 4
compatible ticket. It will store this ticket in the default Kerberos 4
ticket file.
-9
--524convert
only convert ticket to version 4
--afslog
Gets AFS tickets, converts them to version 4 format, and stores them
in the kernel. Only useful if you have AFS.
The
forwardableproxiableticket_life
and
renewable_life
options can be set to a default value from the
appdefaults
section in krb5.conf, see
krb5_appdefault3.
If a
command
is given,
kinit
will setup new credentials caches, and AFS PAG, and then run the given
command. When it finishes the credentials will be removed.
ENVIRONMENT
KRB5CCNAME
Specifies the default credentials cache.
KRB5_CONFIG
The file name of
krb5.conf
, the default being
/etc/krb5.conf
KRBTKFILE
Specifies the Kerberos 4 ticket file to store version 4 tickets in.
