kinit kauth - acquire initial tickets


kinit [-4 | --524init ] [-9 | --524convert ] [--afslog ] [-c cachename | --cache= cachename ] [-f | --forwardable ] [-t keytabname | --keytab= keytabname ] [-l time | --lifetime= time ] [-p | --proxiable ] [-R | --renew ] [--renewable ] [-r time | --renewable-life= time ] [-S principal | --server= principal ] [-s time | --start-time= time ] [-k | --use-keytab ] [-v | --validate ] [-e enctypes | --enctypes= enctypes ] [-a addresses | --extra-addresses= addresses ] [--password-file= filename ] [--fcache-version= version-number ] [-A | --no-addresses ] [--anonymous ] [--version ] [--help ] [principal [command ] ]


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.
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.
--password-file= filename
read the password from the first line of filename If the filename is STDIN the password will be read from the standard input.
--fcache-version= version-number
Create a credentials cache of version version-number
-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.
-A --no-addresses
Request a ticket with no addresses.
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
Gets AFS tickets, converts them to version 4 format, and stores them in the kernel. Only useful if you have AFS.

The forwardable proxiable ticket_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 set up new credentials caches, and AFS PAG, and then run the given command. When it finishes the credentials will be removed.


Specifies the default credentials cache.
The file name of krb5.conf the default being /etc/krb5.conf
Specifies the Kerberos 4 ticket file to store version 4 tickets in.
