DESCRIPTIONkinit 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 Ker‐
beros 4 server, kinit will detect this and get you Kerberos 4 tickets.
-c cachename --cache=cachename
The credentials cache to put the acquired ticket in, if other
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 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 (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.
Try to convert the obtained Kerberos 5 krbtgt to a version 4 com‐
patible ticket. It will store this ticket in the default Ker‐
beros 4 ticket file.
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
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
