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/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).


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.
