- Kerberos configuration utility
kdb5_ldap_util [-D user_dn [-w passwd]] [-H ldap_uri] command
[command_options]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.
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.
The following general options are supported:
Specifies the distinguished name (DN) of a user who has sufficient rights to perform the operation on the LDAP server.
Specifies the URI of the LDAP server.
Specifies the password of user_dn. This option is not recommended.
The following options apply to a number of kdb5_ldap_util commands.
Specifies the list of subtrees containing the principals of a realm. The list contains the DNs of the subtree objects separated by a colon.
Specifies the scope for searching the principals under a subtree. The possible values are 1 or one (one level), 2 or sub (subtrees).
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.
Specifies maximum ticket life for principals in this realm.
Specifies maximum renewable life of tickets for principals in this realm.
Specifies the Kerberos realm of the database; by default the realm returned by krb5_default_local_realm(3) is used.
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 creates a realm in a directory. The command has the following syntax:
create \ [-subtrees subtree_dn_list] [-sscope search_scope] [-containerref container_reference_dn] [-k mkeytype] [-m|-P password| -sf stashfilename] [-s] [-r realm] [-maxtktlife max_ticket_life] [-kdcdn kdc_service_list] [-admindn admin_service_list] [-maxrenewlife max_renewable_ticket_life] [ticket_flags]
The create command has the following options:
See “Common Command-specific Options,” above.
See “Common Command-specific Options,” above.

Specifies the key type of the master key in the database; the default is that given in kdc.conf(4).
Specifies that the master database password should be read from the TTY rather than fetched from a file on the disk.
Specifies the master database password. This option is not recommended.
Specifies the stash file of the master database password.
Specifies that the stash file is to be created.
See “Common Command-specific Options,” above.
See “Common Command-specific Options,” above.
See “Common Command-specific Options,” above.

stashsrvpw [-f filename] servicedn
The stashsrvpw command has the following option and argument:
Specifies the complete path of the service password file. The default is:
/var/krb5/service_passwd
Specifies the distinguished name (DN) of the service object whose password is to be stored in file.
The create_policy command creates a ticket policy in a directory. The command has the following syntax:
create_policy \ [-r realm] [-maxtktlife max_ticket_life] [-maxrenewlife max_renewable_ticket_life] [ticket_flags] policy_name

See “Common Command-specific Options,” above.
Forces the deletion of the policy object. If not specified, you will be prompted for confirmation before the policy is deleted. Enter yes to confirm the deletion.
Specifies the name of the ticket policy.
The list_policy command lists the ticket policies in the default or a specified realm. The command has the following syntax:
list_policy [-r realm]
The list_policy command has the following option:
See “Common Command-specific Options,” above.
A number of kdb5_ldap_util commands have ticket_flag options. These flags are described as follows:
-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 prohibits principals from obtaining forwardable tickets. This setting sets the KRB5_KDB_DISALLOW_FORWARDABLE flag. +allow_forwardable clears this flag.
-allow_postdated prohibits principals from obtaining postdated tickets. This setting sets the KRB5_KDB_DISALLOW_POSTDATED flag. +allow_postdated clears this flag.
-allow_proxiable prohibits principals from obtaining proxiable tickets. This setting sets the KRB5_KDB_DISALLOW_PROXIABLE flag. +allow_proxiable clears this flag.
-allow_renewable prohibits principals from obtaining renewable tickets. This setting sets the KRB5_KDB_DISALLOW_RENEWABLE flag. +allow_renewable clears this flag.
-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 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 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 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 sets a flag in the attributes field marking a principal as a password-change-service principal (a designation 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 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 principals to preauthenticate before being allowed to kinit(1). This setting sets the KRB5_KDB_REQUIRES_PRE_AUTH flag. -requires_preauth clears this flag.
