kinit — acquire initial tickets

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.

       Supported options:

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

       -f--forwardable
               Obtain a ticket than can be forwarded to another host.

       -F--no-forwardable
               Do not obtain a forwardable ticket.

       -tkeytabname, --keytab=keytabname
               Don't ask for a password, but instead get the key from the specified keytab.

       -ltime, --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.

       -rtime, --renewable-life=time
               The max renewable ticket life.

       -Sprincipal, --server=principal
               Get a ticket for a service other than krbtgt/LOCAL.REALM.

       -stime, --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.

       -n, --anonymous
               Request an anonymous ticket.  With the default  (false)  setting  of  the  historical_anon_pkinit
               configuration  parameter,  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 (with fully RFC-
               comformant KDCs) realm in the returned ticket  will  be  anonymized.   Otherwise,  authentication
               proceeds  as  normal  and  the  anonymous ticket will have only the client name anonymized.  With
               historical_anon_pkinit set to true, the principal is interpreted as a realm even without  an  at-
               sign prefix, and it is not possible to obtain authenticated anonymized tickets.

       --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  @
               characters  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
               principal 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 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 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.

       KRB5CCNAME
               Specifies the default credentials cache.

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