<H2>NAME</H2><PRE>
 kinit - obtain and cache Kerberos ticket-granting ticket

</PRE>
<H2>SYNOPSIS</H2><PRE>
 kinit
 [-5] [-4] [-V] [-l lifetime] [-s start_time] [-r
 renewable_life] [-p | -P] [-f | -F] [-a] [-A] [-v] [-R]
 [-k [-t keytab_file]] [-c cache_name] [-S service_name]
 [principal]

</PRE>
<H2>DESCRIPTION</H2><PRE>
 kinit obtains and caches an initial ticket-granting ticket
 for principal. The typical default behavior is to acquire
 only Kerberos 5 tickets. However, if kinit was built with
 both Kerberos 4 support and with the default behavior of
 acquiring both types of tickets, it will try to acquire both
 Kerberos 5 and Kerberos 4 by default. Any documentation
 particular to Kerberos 4 does not apply if Kerberos 4 sup-
 port was not built into kinit.

</PRE>
<H2>OPTIONS</H2><PRE>
 -5 get Kerberos 5 tickets. This overrides whatever the
 default built-in behavior may be. This option may be
 used with -4

-4 get Kerberos 4 tickets. This overrides whatever the
 default built-in behavior may be. This option is only
 available if kinit was built with Kerberos 4 compati-
 bility. This option may be used with -5

-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 life-
 time (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 fed back to the kdc
 before use. (Not applicable to Kerberos 4.)

-r renewable_life
 requests renewable tickets, with a total lifetime of
 renewable_life. The duration is in the same format as
 the -l option, with the same delimiters. (Not applica-
 ble to Kerberos 4.)

-f request forwardable tickets. (Not applicable to Ker-
 beros 4.)

-F do not request forwardable tickets. (Not applicable to
 Kerberos 4.)

-p request proxiable tickets. (Not applicable to Kerberos
 4.)

-P do not request proxiable tickets. (Not applicable to
 Kerberos 4.)

-a request tickets with the local address[es]. (Not
 applicable to Kerberos 4.)

-A request address-less tickets. (Not applicable to Ker-
 beros 4.)

-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.
 (Not applicable to Kerberos 4.)

-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. When using
 this option with Kerberos 4, the kdc must support Ker-
 beros 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. When using this option with Kerberos 4, the kdc
 must support Kerberos 5 to Kerberos 4 ticket conver-
 sion.

-c cache_name
 use cache_name as the Kerberos 5 credentials (ticket)
 cache name and location; if this option is not used,
 the default cache name and location are used.

The default credentials cache may vary between systems.
 If the KRB5CCNAME environment variable is set, its
 value is used to name the default ticket cache. Any
 existing contents of the cache are destroyed by kinit.
 (Note: The default name for Kerberos 4 comes from the
 KRBTKFILE environment variable. This option does not
 apply to Kerberos 4.)

-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.)

</PRE>
<H2>ENVIRONMENT</H2><PRE>
 Kinit uses the following environment variables:

KRB5CCNAME      Location  of  the  Kerberos  5   credentials
                     (ticket) cache.

KRBTKFILE      Filename  of  the  Kerberos   4   credentials
                    (ticket) cache.

</PRE>
<H2>FILES</H2><PRE>
 /tmp/krb5cc_[uid] default location of Kerberos 5 creden-
 tials cache ([uid] is the decimal UID of
 the user).

/tmp/tkt[uid]  default location of  Kerberos  4  credentials
                    cache ([uid] is the decimal UID of the user).

/etc/krb5.keytab
 default location for the local host's keytab
 file.
