NAME

kinit - obtain and cache the Kerberos ticket-granting ticket

SYNOPSIS

kinit [-llife_time] [-sstart_time] [-v][-p][-f][-k[-tkeytab_®lename]] [-rrenewable_life] [-R][-ccache_®lename] [-Sservice-name] [principal]

DESCRIPTION

kinit obtains and caches an initial ticket-granting ticket for the principal.

Options

Requests a ticket with the lifetime value de®ned in life_time. The value for life_time

-llife_time

 

must be followed immediately by one of the following delimiters:

 

s

seconds

 

m

minutes

 

h

hours

 

d

days

 

For example, as in kinit -l 90m for 90 minutes. You cannot mix units; a value of

 

3h30m will result in an error.

 

If the -loption is not speci®ed, the default ticket lifetime (con®gured by each site) is

 

used. Specifying a ticket lifetime longer than the maximum ticket lifetime (con®gured

 

by each site) results in a ticket with the maximum lifetime.

-sstart_time

Requests a postdated ticket, valid starting at start_time. The format for start_time is

 

the same as the -loption, one of the following: seconds, minutes, hours, or days.

 

Postdated tickets are issued with the invalid ¯ag set, and need to be fed back to the

 

Kerberos KDC (Key Distribution Center) before use.

-v

Requests that the ticket granting ticket in the cache (with the invalid ¯ag 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.

-p

Requests proxiable tickets.

-f

Requests forwardable tickets.

-rrenewable_life Requests renewable tickets, with a total lifetime of renewable_life. The format for renewable_life is the same as the -loption, one of the following: seconds, minutes,

 

hours, or days.

-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.

-k[-tkeytab_filename]

Requests a host ticket, obtained from a key in the local host's keytab ®le. The name and location of the keytab ®le may be speci®ed with the -tkeytab_®lename option; otherwise the default name and location will be used.

-ccache_filename Uses cache_®lename as the 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.

-Sservice_name Speci®es an alternate service name to use when getting initial tickets.

principal

Uses the principal name from an existing cache if there is one.

Note

For DCE operations use /opt/dce/bin/kinit.

Environment

kinit uses the following environment variable:

KRB5CCNAME Location of the credentials ticket cache.
