NAME
kdb5_ldap_util - Kerberos configuration utility
SYNOPSIS
kdb5_ldap_util [-D user_dn [-w passwd]] [-H ldap_uri] command [command_options]
DESCRIPTION
The kdb5_ldap_util utility allows an administrator to manage realms, Kerberos services, and ticket policies. The utility offers a set of general options, described under OPTIONS, and a set of commands, which, in turn, have their own options. Commands and their options are described in their own subsections, below.
OPTIONS
kdb5_ldap_util has a small set of general options that apply to the kdb5_ldap_util utility itself and a larger number of options that apply to specific commands. A number of these command-specific options apply to multiple commands and are described in their own section, below. General Options The following general options are supported: -D user_dn Specifies the distinguished name (DN) of a user who has sufficient rights to perform the operation on the LDAP server. -H ldap_uri Specifies the URI of the LDAP server. -w passwd Specifies the password of user_dn. This option is not recommended. Common Command-specific Options The following options apply to a number of kdb5_ldap_util commands. -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 a colon. -sscope search_scope Specifies the scope for searching the principals under a 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 config- ured for a realm, the principals will be created in the realm container. -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. -r realm Specifies the Kerberos realm of the database; by default the realm returned by krb5_default_local_realm(3) is used. kdb5_ldap_util COMMANDS The kdb5_ldap_util utility comprises a set of commands, each with its own set of options. These commands are described in the following subsections. The create Command The create command creates a realm in a directory.

TICKET FLAGS
A number of kdb5_ldap_util commands have ticket_flag options. These flags are described as follows: {-|+}allow_dup_skey -allow_dup_skey disables user-to-user authentication for principals by prohibiting principals from obtaining a session key for another user. This setting sets the KRB5_KDB_DISALLOW_DUP_SKEY flag. +allow_dup_skey clears this flag. {-|+}allow_forwardable -allow_forwardable prohibits principals from obtaining forwardable tickets. This setting sets the KRB5_KDB_DISALLOW_FORWARDABLE flag. +allow_forwardable clears this flag. {-|+}allow_postdated -allow_postdated prohibits principals from obtaining postdated tickets. This setting sets the KRB5_KDB_DISALLOW_POSTDATED flag. +allow_postdated clears this flag. {-|+}allow_proxiable -allow_proxiable prohibits principals from obtaining proxiable tickets. This setting sets the KRB5_KDB_DISALLOW_PROXIABLE flag. +allow_proxiable clears this flag. {-|+}allow_renewable -allow_renewable prohibits principals from obtaining renewable tickets. This setting sets the KRB5_KDB_DISALLOW_RENEWABLE flag. +allow_renewable clears this flag. {-|+}allow_svr -allow_svr prohibits the issuance of service tickets for principals. This setting 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 purposes. +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 the attributes field to force a password change; -needchange clears that flag. 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 a principal as a password-change-service principal (a designa- tion that is most often not useful). -password_changing_service clears the flag. That this flag has a long name is intentional. The default is -password_changing_service. In effect, +password_changing_service sets the KRB5_KDB_PWCHANGE_SERVICE flag on principals in the database. {-|+}requires_hwauth +requires_hwauth requires principals to preauthenticate using a hardware device before being allowed to kinit(1). This setting sets the KRB5_KDB_REQUIRES_HW_AUTH flag. -requires_hwauth clears this flag. {-|+}requires_preauth +requires_preauth requires principals to preauthenticate before being allowed to kinit(1). This setting sets the KRB5_KDB_REQUIRES_PRE_AUTH flag. -requires_preauth clears this flag.
