Sun GlassFish Message Queue 4.4 Administration Guide


A client requesting a connection to a broker must supply a user name and password, which the broker compares with those stored in the user repository. Passwords transmitted from client to broker are encoded using either base-64 encoding (for flat-file repositories) or message digest (MD5) hashing (for LDAP repositories). The choice is controlled by the imq.authentication.type property for the broker as a whole, or by imq.serviceName. authentication.type for a specific connection service. The imq.authentication.client.response.timeout property sets a timeout interval for authentication requests.

As described under Password Files, you can choose to put your passwords in a password file instead of being prompted for them interactively. The boolean broker property imq.passfile.enabled controls this option. If this property is true, the imq.passfile.dirpath and properties give the directory path and file name for the password file. The imq.imqcmd.password property (which can be embedded in the password file) specifies the password for authenticating an administrative user to use the Command utility (imqcmd) for managing brokers, connection services, connections, physical destinations, durable subscriptions, and transactions.

If you are using an LDAP-based user repository, there are a whole range of broker properties available for configuring various aspects of the LDAP lookup. The address (host name and port number) of the LDAP server itself is specified by imq.user_repository.ldap.server. The imq.user_repository.ldap.principal property gives the distinguished name for binding to the LDAP repository, while imq.user_repository.ldap.password supplies the associated password. Other properties specify the directory bases and optional JNDI filters for individual user and group searches, the provider-specific attribute identifiers for user and group names, and so forth; see Security Properties for details.
