This attribute is valid only for an AuthInfoType of MQAIT_IDPW_OS, and is not valid on IBM MQ for z/OS.

AuthorizationMethod (MQCFIN)

MQLDAP_AUTHORMD_OS

Use operating system groups to determine permissions associated with a user.

MQLDAP_AUTHORMD_SEARCHGRP

A group entry in the LDAP repository contains an attribute listing the Distinguished Name of all the users belonging to that group.

MQLDAP_AUTHORMD_SEARCHUSER

A user entry in the LDAP repository contains an attribute listing the Distinguished Name of all the groups to which the specified user belongs.

MQLDAP_AUTHORMD_SRCHGRPSN

A group entry in the LDAP repository contains an attribute listing the short user name of all the users belonging to that group.

BaseDNGroup (MQCFST)

In order to be able to find group names, this parameter must be set with the base DN to search for groups in the LDAP server (parameter identifier MQCA_LDAP_BASE_DN_GROUPS).

The maximum length of the string is MQ_LDAP_BASE_DN_LENGTH.

BaseDNUser (MQCFST)

In order to be able to find the short user name attribute (see ShortUser ) this parameter must be set with the base DN to search for users within the LDAP server.

This attribute is valid only for an AuthInfoType of MQAIT_IDPW_LDAP and is mandatory (parameter identifier MQ_LDAP_BASE_DN_USERS).

The maximum length is MQ_LDAP_BASE_DN_LENGTH.

Checklocal or Checkclient (MQCFIN)

These attributes are valid only for an AuthInfoType of MQAIT_IDPW_OS or MQAIT_IDPW_LDAP (parameter identifier MQIA_CHECK_LOCAL_BINDING or MQIA_CHECK_CLIENT_BINDING). The possible values are:

MQCHK_NONE

Switches off checking.

MQCHK_OPTIONAL

Ensures that if a user ID and password are provided by an application, they are a valid pair, but that it is not mandatory to provide them. This option might be useful during migration, for example.

MQCHK_REQUIRED

Requires that all applications provide a valid user ID and password.

MQCHK_REQUIRED_ADMIN

Privileged users must supply a valid user ID and password, but non-privileged users are treated as with the OPTIONAL setting. See also the following note. (This setting is not allowed on z/OS systems.)

ClassGroup (MQCFST)

The maximum length is MQ_LDAP_CLASS_LENGTH.

FailureDelay (MQCFIN)

The failure delay (parameter identifier MQIA_AUTHENTICATION_FAIL_DELAY) when an authentication fails due to the user ID or password being incorrect, in seconds, before the failure is returned to the application.

The maximum length is MQ_LDAP_PASSWORD_LENGTH.

This parameter is relevant only when AuthInfoType is set to MQAIT_CRL_LDAP or MQAIT_IDPW_LDAP.

The Distinguished Name of the user who is binding to the directory.

The maximum length is MQ_DISTINGUISHED_NAME_LENGTH. On z/OS, it is MQ_SHORT_DNAME_LENGTH.

A field in the user record to be used as a short user name in IBM MQ (parameter identifier MQCA_LDAP_SHORT_USER_FIELD)..

The maximum length is MQ_LDAP_FIELD_LENGTH.

UserField (MQCFST)

Identifies the field in the LDAP user record that is used to interpret the provided user ID, only if the user ID does not contain a qualifier (parameter identifier MQCA_LDAP_USER_ATTR_FIELD).

The maximum length is MQ_LDAP_FIELD_LENGTH.
