DESCRIPTION
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.
Supported options:
-
-c cachename --cache=cachename
-
The credentials cache to put the acquired ticket in, if other than default.
-
-f --no-forwardable
-
Get ticket that can be forwarded to another host, or if the negative flags use, don't get a forwardable flag.
-
-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.
-
--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.conf(5).
-
-A, --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”).
-
--enterprise
-
Parse principal as a enterprise (KRB5-NT-ENTERPRISE) name. Enterprise names are email like principals that are stored in the name part of the principal, and since there are two @ characters the parser needs to know that the first is not a realm. An example of an enterprise name is “lha@e.kth.se@KTH.SE”, and this option is usually used with canonicalize so that the principal returned from the KDC will typically be the real principal name.
-
--afslog
-
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_appdefault(3).
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.
