Authorization rules with the resource type connection control access to the broker’s connection services. The rule’s resourceVariant element specifies the service type of the connection services to which the rule applies, as shown in Table 6–1; the only possible values are NORMAL or ADMIN. There is no operation element.
The default access control file contains the rules
giving all users access to NORMAL connection services (jms, ssljms, httpjms, and httpsjms) and those in the admin group access to ADMIN connection services (admin and ssladmin). You can then add additional authorization rules to restrict the connection access privileges of specific users: for example, the rule
denies user Snoopy access privileges for connection services of type NORMAL.
If you are using a file-based user repository, the admin user group is created by the User Manager utility. If access control is disabled (imq.accesscontrol.enabled = false), all users in the admin group automatically have connection privileges for ADMIN connection services. If access control is enabled, access to these services is controlled by the authorization rules in the access control file.
If you are using an LDAP user repository, you must define your own user groups in the LDAP directory, using the tools provided by your LDAP vendor. You can either define a group named admin, which will then be governed by the default authorization rule shown above, or edit the access control file to refer to one or more other groups that you have defined in the LDAP directory. You must also explicitly enable access control by setting the broker’s imq.accesscontrol.enabled property to true.
