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
	     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.

     -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 set-
	     table via libdefaults/extra_addresses in krb5.conf(5).

     --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.

     -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.

     -9, --524convert
	     only convert ticket to version 4

     --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 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.
