     kgetcred — get a ticket for a particular service

SYNOPSIS

     kgetcred [--canonicalize] [--canonical] [-c -cache | --cache=cache] [-e enctype |
              --enctype=enctype] [--debug] [-H | --hostbased] [--name-type=name-type]
              [--no-transit-check] [--no-store] [--cached-only] [-n | --anonymous] [--version]
              [--help] principal
     kgetcred [options] --hostbased principal
     kgetcred [options] --hostbased service hostname [extra-components]

DESCRIPTION

     kgetcred obtains a ticket for the given service principal.  Usually tickets for services are
     obtained automatically when needed but sometimes for some odd reason you want to obtain a
     particular ticket or of a special type.

     If --hostbased is given then the given service principal name will be canonicalized (see
     below).

     The third form constructs a host-based principal from the given service name and hostname.
     The service name "host" is used if the given service name in the third usage is the empty
     string.

     For host-based names, the local host's hostname is used if the given hostname is the empty
     string or if the principal has a single component.

     Any additional components will be included, even for host-based service principal names, but
     there are no defaults nor local canonicalization rules for additional components.

     Local name canonicalization rules are applied unless the --canonical option is given.
     Currently local name canonicalization rules are supported only for host-based principal
     names' hostname component.

     The principal's realm name may be canonicalized by following Kerberos referrals from the
     client principal's home realm if the --canonicalize option is given or if the local name
     canonicalization rules are configured to use referrals.

     Supported options:

     --canonicalize
             requests that the KDC canonicalize the principal.  Currently this only canonicalizes
             the realm by chasing referrals from the user's start realm, but in the future this
             may also enable the KDC to canonicalize the complete principal name.

     --canonical
             turns off local canonicalization of the principal name.

     --name-type=name-type
             the name-type to use when parsing the principal name.

     --hostbased
             is short for --name-type=srv_hst.

     -c cache, --cache=cache
             the credential cache to use.

     --delegation-credential-cache=cache
             the credential cache to use for delegation.

     -e enctype, --enctype=enctype
             encryption type to use.

     --no-transit-check
             requests that the KDC doesn't do transit checking.

     --no-store
             do not store tickets in the ccache.

     --cached-only
             do not talk the TGS, search only the ccache.

     --anonymous
             obtain an anonymous service ticket.

     --forwardable

     --debug
             enables debug output to stderr.

     --version

     --help

     If the --canonical option is used, then no further canonicalization should be done locally
     by the client (for example, DNS), but if --canonicalize is used, then the client will ask
     that the KDC canonicalize the name.

     If the --canonicalize option is used with --hostbased a host-based name-type, and
     --canonical is not used, then the hostname will be canonicalized according to the name
     canonicalization rules in krb5.conf.

     GSS-API initiator applications with host-based services will get the same behavior as using
     the --canonicalize --hostbased options here.
