9.13. ACL Lookup Query Methods

QMF methods are available to query the ACL Authorization interface.

The Broker must be started with the ACL file that you wish to query, and that ACL file must include sufficient permissions to allow the lookup operations:

Catch 22: allow anonymous to access the lookup debug functions

# Catch 22: allow anonymous to access the lookup debug functions
acl allow-log anonymous create  queue
acl allow-log anonymous all     exchange name=qmf.*
acl allow-log anonymous all     exchange name=amq.direct
acl allow-log anonymous all     exchange name=qpid.management
acl allow-log anonymous access  method   name=Lookup*

The QMF methods to query the ACL Authorization interface are Lookup and LookupPublish.

The Lookup method is a general query for any action, object, and set of properties. The LookupPublish method is the optimized, per-message fastpath query.

In both methods the result is one of: allow, deny, allow-log, or deny-log.

Procedure 9.1. ACL Lookup Example

To see a practical example, follow these steps.

Start the broker using the example ACL file acl-test-01-rules.acl reproduced below, and with QPID_LOG_ENABLE=debug+:acl.
Run the Python script acl-test-01.py.
Examine the Python program output and the broker log.

ACL File `acl-test-01-rules.acl`

to anything. Everything/everyone else must not be as permissive
Catch 22: allow anonymous to access the lookup debug functions

Publish
Consumers - everyone
All else is denied
