kinit — acquire
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.
- The credentials cache to put the acquired ticket in, if other than default.
- Obtain a ticket than can be forwarded to another host.
- Do not obtain a forwardable ticket.
- Don't ask for a password, but instead get the key from the specified keytab.
- 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.
- The max renewable ticket life.
- Get a ticket for a service other than krbtgt/LOCAL.REALM.
- 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 settable via
- 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 unauthenticated anonymous ticket and both the client name and realm in the returned ticket will be anonymized. Otherwise, authentication proceeds as normal and the anonymous ticket will have only the client name anonymized.
- 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 “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.
proxiable, ticket_life, and
renewable_life options can be set to a default value

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
