           [--fcache-version=version-number] [-A | --no-addresses] [--anonymous] [--enterprise] [--version]
           [--help] [principal [command]]

DESCRIPTION
     kinit is used to authenticate to the Kerberos server as principal, or if none is given, a system gener-ated generated
     ated 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.

     Supported options:

     -c cachename --cache=cachename
             The credentials cache to put the acquired ticket in, if other than default.

     -canonicalize
             ask the KDC canonicalize the client name and server name. Useful with enterprise names, PK-INIT, PKINIT,
             INIT, and LKDC realms when the user doesn't know its real kerberos user name.

     -f, --forwardable
             Get ticket that can be forwarded to another host.

     -t keytabname, --keytab=keytabname

     -f --no-forwardable
             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'.

     -p, --proxiable
             Request tickets with the proxiable flag set.

     -R, --renew
             Try to renew ticket.  The ticket must have the `renewable' flag set, and must not be expired.

     --renewable
             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.

     -k, --use-keytab
             The same as --keytab, but with the default keytab name (normally FILE:/etc/krb5.keytab).

     -v, --validate
             Try to validate an invalid ticket.

     -e, --enctypes=enctypes
             Request tickets with this particular enctype.

     --password-file=filename
             read the password from the first line of filename.  If the filename is STDIN, the password will
             be read from the standard input.

     --fcache-version=version-number
             Create a credentials cache of version version-number.

     -a, --extra-addresses=enctypes
             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).

     -A, --no-addresses
             Request a ticket with no addresses.

     --anonymous
             Request an anonymous ticket (which means that the ticket will be issued to an anonymous princi-pal, principal,
             pal, typically ``anonymous@REALM'').

     -V, --verbose
             Print slightly more verbose output from kinit when successful.

     --enterprise
             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 @ charac-ters characters
             ters the parser needs to know that the first is not a realm.  An example of an enterprise name
             is ``lha@e.kth.se@KTH.SE'', and this option is usually used with canonicalize so that the prin-cipal principal
             cipal returned from the KDC will typically be the real principal name.

     --afslog
             Gets AFS tickets, converts them to version 4 format, and stores them in the kernel.  Only use-ful useful
             ful 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 krb5_appdefault(3).

     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.

ENVIRONMENT
     KRB5CCNAME
             Specifies the default credentials cache.

     KRB5_CONFIG
             The file name of krb5.conf, the default being /etc/krb5.conf.

     KRBTKFILE
             Specifies the Kerberos 4 ticket file to store version 4 tickets in.
