[--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.
-c cachename --cache=cachename
The credentials cache to put the acquired ticket in, if other
Obtain a ticket than can be forwarded to another host.
Do not obtain a forwardable ticket.
-t keytabname, --keytab=keytabname
Don't ask for a password, but instead get the key from the speci-
-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'.
Request tickets with the proxiable flag set.
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.
The same as --keytab, but with the default keytab name (normally
Try to validate an invalid ticket.
Request tickets with this particular enctype.
read the password from the first line of filename. If the
filename is STDIN, the password will be read from the standard
Create a credentials cache of version version-number.
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).
Request a ticket with no addresses.
Request an anonymous ticket. If the principal is specified as
@REALM, then anonymous PKINIT will be used to acquire an unau-
thenticated anonymous ticket and both the client name and realm
in the returned ticket will be anonymized. Otherwise, authenti-
cation proceeds as normal and the anonymous ticket will have only
the client name anonymized.
Parse principal as a enterprise (KRB5-NT-ENTERPRISE) name. Enter-
prise 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 ``email@example.com@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.
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
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.
