kdb5_ldap_util: Kerberos Configuration Utility

NAME
kdb5_ldap_util - Kerberos Configuration Utility

SYNOPSIS

kdb5_ldap_util [-D user_dn [-w passwd]] [-H ldapuri] command [command_options]

DESCRIPTION

kdb5_ldap_util allows an administrator to manage realms, Kerberos services and ticket policies.

COMMAND-LINE OPTIONS

-D user_dn Specifies the Distinguished name (DN) of the user who has sufficient rights to perform the operation on the LDAP server. -w passwd Specifies the password of user_dn. This option is not recommended. -H ldapuri Specifies the URI of the LDAP server.

COMMANDS

create [-subtrees subtree_dn_list] [-sscope search_scope] [-containerref container_reference_dn] [-k mkeytype] [-kv mkeyVNO] [-m|-P password|-sf stashfilename] [-s] [-r realm] [-kdcdn kdc_service_list] [-admindn admin_service_list] [-maxtktlife max_ticket_life] [-maxrenewlife max_renewable_ticket_life] [ticket_flags] Creates realm in directory. Options: -subtrees subtree_dn_list Specifies the list of subtrees containing the principals of a realm. The list contains the DNs of the subtree objects separated by colon(:). -sscope search_scope Specifies the scope for searching the principals under the subtree. The possible values are 1 or one (one level), 2 or sub (subtrees). -containerref container_reference_dn Specifies the DN of the container object in which the principals of a realm will be created. If the container reference is not configured for a realm, the principals will be created in the realm container. -k mkeytype Specifies the key type of the master key in the database; the default is that given in kdc.conf. -kv mkeyVNO Specifies the version number of the master key in the database; the default is 1. Note that 0 is not allowed. -m Specifies that the master database password should be read from the TTY rather than fetched from a file on the disk. -P password Specifies the master database password. This option is not recommended. -sf stashfilename Specifies the stash file of the master database password. -s Specifies that the stash file is to be created. -maxtktlife max_ticket_life Specifies maximum ticket life for principals in this realm. -maxrenewlife max_renewable_ticket_life Specifies maximum renewable life of tickets for principals in this realm. ticket_flags Specifies the ticket flags. If this option is not specified, by default, none of the flags are set. This means all the ticket options will be allowed and no restriction will be set. The various flags are: {-|+}allow_postdated -allow_postdated prohibits principals from obtaining postdated tickets. (Sets the KRB5_KDB_DISALLOW_POSTDATED flag.) +allow_postdated clears this flag. {-|+}allow_forwardable -allow_forwardable prohibits principals from obtaining forwardable tickets. (Sets the KRB5_KDB_DISALLOW_FORWARDABLE flag.) +allow_forwardable clears this flag. {-|+}allow_renewable -allow_renewable prohibits principals from obtaining renewable tickets. (Sets the KRB5_KDB_DISALLOW_RENEWABLE flag.) +allow_renewable clears this flag. {-|+}allow_proxiable -allow_proxiable prohibits principals from obtaining proxiable tickets. (Sets the KRB5_KDB_DISALLOW_PROXIABLE flag.) +allow_proxiable clears this flag. {-|+}allow_dup_skey -allow_dup_skey Disables user-to-user authentication for principals by prohibiting principals from obtaining a session key for another user. (Sets the KRB5_KDB_DISALLOW_DUP_SKEY flag.) +allow_dup_skey clears this flag. {-|+}requires_preauth +requires_preauth requires principals to preauthenticate before being allowed to kinit. (Sets the KRB5_KDB_REQUIRES_PRE_AUTH flag.) -requires_preauth clears this flag. {-|+}requires_hwauth +requires_hwauth requires principals to preauthenticate using a hardware device before being allowed to kinit. (Sets the KRB5_KDB_REQUIRES_HW_AUTH flag.) -requires_hwauth clears this flag. {-|+}allow_svr -allow_svr prohibits the issuance of service tickets for principals. (Sets the KRB5_KDB_DISALLOW_SVR flag.) +allow_svr clears this flag. {-|+}allow_tgs_req -allow_tgs_req specifies that a Ticket-Granting Service (TGS) request for a service ticket for principals is not permitted. This option is useless for most things. +allow_tgs_req clears this flag. The default is +allow_tgs_req. In effect, -allow_tgs_req sets the KRB5_KDB_DISALLOW_TGT_BASED flag on principals in the database. {-|+}allow_tix -allow_tix forbids the issuance of any tickets for principals. +allow_tix clears this flag. The default is +allow_tix. In effect, -allow_tix sets the KRB5_KDB_DISALLOW_ALL_TIX flag on principals in the database. {-|+}needchange +needchange sets a flag in attributes field to force a password change; -needchange clears it. The default is -needchange. In effect, +needchange sets the KRB5_KDB_REQUIRES_PWCHANGE flag on principals in the database. {-|+}password_changing_service +password_changing_service sets a flag in the attributes field marking principal as a password change service principal (useless for most things). -password_changing_service clears the flag. This flag intentionally has a long name. The default is -password_changing_service. In effect, +password_changing_service sets the KRB5_KDB_PWCHANGE_SERVICE flag on principals in the database. -r realm Specifies the Kerberos realm of the database; by default the realm returned by krb5_default_local_realm(3) is used.
