NAME
kinit - obtain and cache Kerberos ticket-granting ticketSYNOPSIS
- kinit
- [-V] [-l lifetime] [-s start_time] [-r renewable_life] [-p | -P] [-f | -F] [-a] [-A] [-C] [-E] [-v] [-R] [-k [-t keytab_file]] [-c cache_name] [-S service_name][-T armor_ccache] [-X attribute[=value]] [principal]
DESCRIPTION
kinit obtains and caches an initial ticket-granting ticket for principal.OPTIONS
- -V
- display verbose output.
- -l lifetime
- requests a ticket with the lifetime lifetime. The value for lifetime must be followed immediately by one of the following delimiters:
s seconds m minutes h hours d days
as in "kinit -l 90m". You cannot mix units; a value of `3h30m' will result in an error.
If the -l option is not specified, the default ticket lifetime (configured by each site) is used. Specifying a ticket lifetime longer than the maximum ticket lifetime (configured by each site) results in a ticket with the maximum lifetime.
- -s start_time
- requests a postdated ticket, valid starting at start_time. Postdated tickets are issued with the invalid flag set, and need to be fed back to the kdc before use.
- -r renewable_life
- requests renewable tickets, with a total lifetime of renewable_life. The duration is in the same format as the -l option, with the same delimiters.
- -f
- request forwardable tickets.
- -F
- do not request forwardable tickets.
- -p
- request proxiable tickets.
- -P
- do not request proxiable tickets.
- -a
- request tickets with the local address[es].
- -A
- request address-less tickets.
- -C
- requests canonicalization of the principal name.
- -E
- treats the principal name as an enterprise name.
- -v
- requests that the ticket granting ticket in the cache (with the invalid flag set) be passed to the kdc for validation. If the ticket is within its requested time range, the cache is replaced with the validated ticket.
- -R
- requests renewal of the ticket-granting ticket. Note that an expired ticket cannot be renewed, even if the ticket is still within its renewable life.
- -k [-t keytab_file]
- requests a host ticket, obtained from a key in the local host's keytab file. The name and location of the keytab file may be specified with the -t keytab_file option; otherwise the default name and location will be used.
- -T armor_ccache
- Specifies the name of a credential cache that already contains a ticket. This ccache will be used to armor the request. Ideally, an attacker should have to attack both the armor ticket and the key of the principal.
- -c cache_name
- use cache_name as the Kerberos 5 credentials (ticket) cache name and location; if this option is not used, the default cache name and location are used.
The default credentials cache may vary between systems. If the KRB5CCNAME environment variable is set, its value is used to name the default ticket cache. Any existing contents of the cache are destroyed by kinit.
- -S service_name
- specify an alternate service name to use when getting initial tickets.
- -X attribute[=value]
- specify a pre-authentication attribute and value to be passed to pre-authentication plugins. The acceptable attribute and value values vary from pre-authentication plugin to plugin. This option may be specified multiple times to specify multiple attributes. If no value is specified, it is assumed to be "yes".
The following attributes are recognized by the OpenSSL pkinit pre-authentication mechanism: X509_user_identity=value specify where to find user's X509 identity information X509_anchors=value specify where to find trusted X509 anchor information flag_RSA_PROTOCOL[=yes] specify use of RSA, rather than the default Diffie-Hellman protocol
ENVIRONMENT
Kinit uses the following environment variables:- KRB5CCNAME
- Location of the Kerberos 5 credentials (ticket) cache.
FILES
- /tmp/krb5cc_[uid]
- default location of Kerberos 5 credentials cache ([uid] is the decimal UID of the user).
- /etc/krb5.keytab
- default location for the local host's keytab file.
