KINIT(1) General Commands Manual KINIT(1) NAME kinit -- acquire initial tickets SYNOPSIS kinit [--afslog] [-c cachename | --cache=cachename] [-f | --forwardable] [-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 --forwardable Obtain a ticket than can be forwarded to another host. -F --no-forwardable Do not obtain a forwardable ticket. -t keytabname, --keytab=keytabname Don't ask for a password, but instead get the key from the specified 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. Enterprise 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 ``firstname.lastname@example.org@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.
