---------------------------------
Summary: C++ Broker could use username substitution keyword
strings in Acl rules
Key: QPID-4230
URL: https://issues.apache.org/jira/browse/QPID-4230
Project: Qpid
Issue Type: Improvement
Components: C++ Broker
Affects Versions: 0.19
Reporter: Chuck Rolke
Assignee: Chuck Rolke
Acl processing in the broker could perform username substitution into Acl
rules. This would provide an easy and flexible way to constrain users.
1. Let the literal string ${user} be the keyword placed into Acl files.
2. When expanded ${user} will become the full authenticated userId such as
'bob@QPID'. Note that simply using 'bob' leads to issues distinguishing between
'bob@QPID' and '[email protected]'.
3. Username keyword substitution is performed only on object names and in
routing keys.
Acl rule file examples:
acl allow all create exchange name=temp-${user}
acl allow all access exchange name=temp-${user}
acl allow all bind exchange name=temp-${user}
acl allow all unbind exchange name=temp-${user}
acl allow all delete exchange name=temp-${user}
acl allow all publish exchange name=temp-${user} routingkey=temp.${user}
acl allow all create queue name=temp-${user}
acl allow all access queue name=temp-${user}
acl allow all purge queue name=temp-${user}
acl allow all consume queue name=temp-${user}
acl allow all delete queue name=temp-${user}
Using a rule set like this would allow all users to create a private temp-
exchange and a private temp- queue bound to their user names.
