NAME
     kinit — acquire initial tickets

SYNOPSIS
     kinit [--afslog] [-c cachename | --cache=cachename]
	   [-f | --no-forwardable] [-t keytabname | --keytab=keytabname] [-l
	   time | --lifetime=time] [-p | --proxiable] [-R | --renew]
	   [--renewable] [-r time | --renewable-life=time] [-S principal |
	   --server=principal] [-s time | --start-time=time]
	   [-k | --use-keytab] [-v | --validate] [-e enctypes |
	   --enctypes=enctypes] [-a addresses | --extra-addresses=addresses]
	   [--password-file=filename] [--fcache-version=version-number]
	   [-A | --no-addresses] [--anonymous] [--enterprise] [--version]
	   [--help] [principal [command]]

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.

     Supported options:

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

     -f --no-forwardable
	     Get ticket that can be forwarded to another host, or if the nega‐
	     tive flags use, don't get a forwardable flag.

     -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.

     --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.

     --anonymous
	     Request an anonymous ticket (which means that the ticket will be
	     issued to an anonymous principal, typically “anonymous@REALM”).

     --enterprise
	     Parse principal as a enterprise (KRB5-NT-ENTERPRISE) name. Enter‐
	     prise 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.

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.
