DESCRIPTION
     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.

     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.

     Supported options:

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

     -f, --forwardable
             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-
             fied 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/kerberosV/krb5.keytab).

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

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

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

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

     --anonymous
             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. The kauth program is identical to kinit, but has
     these options enabled by default.

     -4, --524init
             Try to convert the obtained Kerberos 5 krbtgt to a version 4 com-
             patible ticket. It will store this ticket in the default Kerberos
             4 ticket file.

     --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 setup 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 cache file.

     KRB5_CONFIG
             The directory where the krb5.conf can be found, default is /etc.

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