NAME
kinit - obtain and cache Kerberos ticket-granting ticket
SYNOPSIS
kinit [-V] [-l lifetime] [-s start_time] [-r renewable_life] [-p | -P]
[-f | -F] [-a | -A] [-v] [-R] [-k [-t keytab_file]] [-S ser-
vice_name] [principal]
DESCRIPTION
kinit obtains and caches an initial ticket-granting ticket for princi-
pal. Any existing tickets for principal are overwritten. kinit will
try to acquire both Kerberos 5 and Kerberos 4 initial tickets if the
appropriate configuration information is available.
OPTIONS
-V display verbose output.
-l lifetime
requests a ticket with the lifetime lifetime. The value for
lifetime must be followed immediately by one of the following
delimiters:
s seconds
m minutes
h hours
d days
as in "kinit -l 90m". You cannot mix units; a value of '3h30m'
will result in an error.
If the -l option is not specified, the default ticket lifetime
(configured by each site) is used. Specifying a ticket lifetime
longer than the maximum ticket lifetime (configured by each
site) results in a ticket with the maximum lifetime.
-s start_time
requests a postdated ticket, valid starting at start_time.
Postdated tickets are issued with the invalid flag set, and need
to be validated by the kdc before use.
-r renewable_life
requests renewable tickets, with a total lifetime of renew-
able_life. The duration is in the same format as the -l option,
with the same delimiters.
-f request forwardable tickets.
-F request tickets which are not forwardable.
-p request proxiable tickets.
-P request tickets which are not proxiable.
-a request tickets containing the host's local address(es).
-A request address-less tickets.
-v requests that the ticket granting ticket in the cache (with the
invalid flag set) be passed to the kdc for validation. If the
ticket is within its requested time range, the cache is replaced
with the validated ticket.
-R requests renewal of the ticket-granting ticket. Note that an
expired ticket cannot be renewed, even if the ticket is still
within its renewable life. This option will only get Kerberos 4
tickets if the kdc must support Kerberos 5 to Kerberos 4 ticket
conversion.
-k [-t keytab_file]
requests a host ticket, obtained from a key in the local host's
keytab file. The name and location of the keytab file may be
specified with the -t keytab_file option; otherwise the default
name and location will be used. This option will only get Ker-
beros 4 tickets if the kdc must support Kerberos 5 to Kerberos 4
ticket conversion.
-S service_name
specify an alternate service name to use when getting initial
tickets. (Applicable to Kerberos 5 or if using both Kerberos 5
and Kerberos 4 with a kdc that supports Kerberos 5 to Kerberos 4
ticket conversion.)
FILES
/etc/krb5.keytab
default location for the local host's keytab file.
