KCM(8) BSD System Manager's Manual KCM(8) NAME
kcm -- is a process based credential cache for Kerberos tickets. SYNOPSIS
kcm [--cache-name=cachename] [-c file | --config-file=file] [-g group | --group=group] [--max-request=size] [--disallow-getting-krbtgt] [--detach] [-h | --help] [-k principal | --system-principal=principal] [-l time | --lifetime=time] [-m mode | --mode=mode] [-n | --no-name-constraints] [-r time | --renewable-life=time] [-s path | --socket-path=path] [--door-path=path] [-S principal | --server=principal] [-t keytab | --keytab=keytab] [-u user | --user=user] [-v | --version] DESCRIPTION
kcm is a process based credential cache. To use it, set the KRB5CCNAME enviroment variable to 'KCM:uid' or add the stanza [libdefaults] default_cc_name = KCM:%{uid} to the /etc/krb5.conf configuration file and make sure kcm is started in the system startup files. The kcm daemon can hold the credentials for all users in the system. Access control is done with Unix-like permissions. The daemon checks the access on all operations based on the uid and gid of the user. The tickets are renewed as long as is permitted by the KDC's policy. The kcm daemon can also keep a SYSTEM credential that server processes can use to access services. One example of usage might be an nss_ldap module that quickly needs to get credentials and doesn't want to renew the ticket itself. Supported options: --cache-name=cachename system cache name -c file, --config-file=file location of config file -g group, --group=group system cache group --max-request=size max size for a kcm-request --disallow-getting-krbtgt disallow extracting any krbtgt from the kcm daemon. --detach detach from console -h, --help -k principal, --system-principal=principal system principal name -l time, --lifetime=time lifetime of system tickets -m mode, --mode=mode octal mode of system cache -n, --no-name-constraints disable credentials cache name constraints -r time, --renewable-life=time renewable lifetime of system tickets -s path, --socket-path=path path to kcm domain socket --door-path=path path to kcm door socket -S principal, --server=principal server to get system ticket for -t keytab, --keytab=keytab system keytab name -u user, --user=user system cache owner -v, --version BSD

KINIT(1) General Commands Manual KINIT(1) NAME
kinit - obtain and cache Kerberos ticket-granting ticket SYNOPSIS
kinit [-5] [-4] [-V] [-l lifetime] [-s start_time] [-r renewable_life] [-p | -P] [-f | -F] [-A] [-v] [-R] [-k [-t keytab_file]] [-c cache_name] [-S service_name] [principal] DESCRIPTION
kinit obtains and caches an initial ticket-granting ticket for principal.Thetypicaldefaultbehavioristoacquireonly Kerberos 5 tickets. How- ever, if kinit was built with both Kerberos 4 support and with the default behavior of acquiring both types of tickets, it will try to acquire both Kerberos 5 and Kerberos 4 by default. Any documentation particular to Kerberos 4 does not apply if Kerberos 4 support was not built into kinit. OPTIONS
-5 get Kerberos 5 tickets. This overrides whatever the default built-in behavior may be. This option may be used with -4 -4 get Kerberos 4 tickets. This overrides whatever the default built-in behavior may be. This option is only available if kinit was built with Kerberos 4 compatibility. This option may be used with -5 -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 delim- iters: 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. (Not applicable to Kerberos 4.) -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. (Not applicable to Kerberos 4.) -f request forwardable tickets. (Not applicable to Kerberos 4.) -F do not request forwardable tickets. (Not applicable to Kerberos 4.) -p request proxiable tickets. (Not applicable to Kerberos 4.) -P do not request proxiable tickets. (Not applicable to Kerberos 4.) -A request address-less tickets. (Not applicable to Kerberos 4.) -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. (Not applicable to Kerberos 4.) -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. When using this option with Kerberos 4, the kdc must support Kerberos 5 to Kerberos 4 ticket conversion. -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 speci- fied with the -t keytab_file option; otherwise the default name and location will be used. When using this option with Kerberos 4, the kdc must support Kerberos 5 to Kerberos 4 ticket conversion. -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. (Note: The default name for Kerberos 4 comes from the KRBTKFILE environment variable. This option does not apply to Kerberos 4.) -S service_name specify an alternate service name to use when getting initial tickets. (Applicable to Kerberos 5 or if using both Kerberos 5 and Kerberos 4 with a kdc that supports Kerberos 5 to Kerberos 4 ticket conversion.) ENVIRONMENT
Kinit uses the following environment variables: KRB5CCNAME Location of the Kerberos 5 credentials (ticket) cache. KRBTKFILE Filename of the Kerberos 4 credentials (ticket) cache. FILES
/tmp/krb5cc_[uid] default location of Kerberos 5 credentials cache ([uid] is the decimal UID of the user). /tmp/tkt[uid] default location of Kerberos 4 credentials cache ([uid] is the decimal UID of the user). /etc/krb5.keytab default location for the local host's keytab file. SEE ALSO
