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
-c cachename --cache=cachename
The credentials cache to put the acquired ticket in,
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
-l time, --lifetime=time
Specifies the lifetime of the ticket. The argument
can either be
in seconds, or a more human readable string like
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
Try to validate an invalid ticket.
Request tickets with this particular enctype.
Create a credentials cache of version version.
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
One such example is if the client is behind a firewall. Also settable
via libdefaults/extra_addresses in
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
support for Kerberos 4.
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.
only convert ticket to version 4
Gets AFS tickets, converts them to version 4 format,
them in the kernel. Only useful if you have AFS.
The forwardable, proxiable, ticket_life, and renewable_life
be set to a default value from the appdefaults section in
If a command is given, kinit will setup new credentials
caches, and AFS
PAG, and then run the given command. When it finishes the
will be removed.
Specifies the default credentials cache.
