[--enterprise] [--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.
-c cachename --cache=cachename
The credentials cache to put the acquired ticket in, if other than default.
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'.
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 FILE:/etc/krb5.keytab).
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 input.
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 set-
table 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'').
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 ``firstname.lastname@example.org@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,
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 creden-
tials 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.
