LDAP attributes

LDAP attributes defined are specific to IBM MQ and maps directly to the client connection properties.

IBM MQ Client Channel Directory String Attributes

The character string attributes with their mapping to IBM MQ properties are listed in the following table. The attributes can hold values of directoryString (UTF-8 encoded Unicode, that is, a variable byte encoding system that includes IA5/ASCII as a subset) syntax. The syntax is specified by its object identification number (OID).

IBM MQ client connection integer attributes

The attributes with predefined values (for example, an enumerated type) are stored as standard integers. These values are stored in the LDAP directory as integer values, and not by using the associated constant name.

IBM MQ client channel boolean attribute

This Boolean attribute is not mapped to any IBM MQ property. The syntax of this attribute indicates a boolean value.

IBM MQ client channel list attributes

IBM MQ properties are stored as single-value, comma-separated list attribute within the LDAP directory. The attributes are defined in the same manner as the other directory string attributes. The list attributes along with their mapping to the IBM MQ properties are described in the following table.

• Common Name
  The common name (CN) consists of the channel name and the defining queue manager name.
• ibm-amqChannelName
  This attribute specifies the name of the channel definition.
• ibm-amqDescription
  This LDAP attribute provides the channel description.
• ibm-amqConnectionName
  This LDAP attribute is the communications connection identifier. It specifies the particular communications links to be used by this channel.
• ibm-amqLocalAddress
  This attribute specifies the local communications address for the channel.
• ibm-amqModeName
  This attribute is for use with LU 6.2 connections. It gives extra definition for the session characteristics of the connection when a communication session allocation is performed.
• ibm-amqPassword
  This LDAP attribute specifies a password that can be used by the MCA when attempting to initiate a secure LU 6.2 session with a remote MCA.
• ibm-amqQueueManagerName
  This attribute specifies the name of the queue manager or queue manager group to which an IBM MQ client application can request connection.
• ibm-amqSecurityExitUserData
  This LDAP attribute specifies user data that is passed to the security exit.
• ibm-amqSecurityExitName
  This LDAP attribute specifies the name of the exit program to be run by the channel security exit.
• ibm-amqSslCipherSpec
  This LDAP attribute specifies a single CipherSpec for a TLS connection.
• ibm-amqSslPeerName
  This LDAP attribute is used to check the Distinguished Name (DN) of the certificate from the peer queue manager or client at the other end of an IBM MQ channel.
• ibm-amqTransactionProgramName
  This LDAP attribute specifies the transaction program name. It is for use with LU 6.2 connections.
• ibm-amqUserID
  This LDAP attribute specifies the user ID to be used by the MCA when attempting to initiate a secure SNA session with a remote MCA.
• ibm-amqConnectionAffinity
  This LDAP attribute specifies whether client applications, which connect multiple times using the same queue manager name, use the same client channel.
• ibm-amqClientChannelWeight
  This LDAP attribute specifies a weighting that influences which client connection channel definition is used.
• ibm-amqHeartBeatInterval
  This LDAP attribute specifies the approximate time between heartbeat flows that are to be passed from a sending MCA when there are no messages on the transmission queue.
• ibm-amqKeepAliveInterval
  This LDAP attribute is used to specify a time-out value for a channel.
• ibm-amqMaximumMessageLength
  This LDAP attribute specifies the maximum length of a message that can be transmitted on the channel.
• ibm-amqSharingConversations
  This LDAP attribute specifies the maximum number of conversations that share each TCP/IP channel instance.
• ibm-amqTransportType
  This LDAP attribute specifies the transport type to be used.
• ibm-amqIsClientDefault
  This Boolean attribute solves the problem of searching entries where the ibm-amqQueueManagerName attribute has not been defined.
• ibm-amqHeaderCompression
  This LDAP attribute is a list of header data compression techniques supported by the channel.
• ibm-amqMessageCompression
  This LDAP attribute is a list of message data compression techniques supported by the channel.
• ibm-amqSendExitUserData
  This LDAP attribute specifies user data that is passed to the send exit.
• ibm-amqSendExitName
  This LDAP attribute specifies the name of the exit program to be run by the channel send exit.
• ibm-amqReceiveExitUserData
  This LDAP attribute specifies user data that is passed to the receive exit.
• ibm-amqReceiveExitName
  This LDAP attribute specifies the name of the user exit program to be run by the channel receive user exit.
