Andrew Kennedy commented on QPID-2539:
--------------------------------------

RA:
1. I don't think we should deprecate the "group" declarations. I think it's a 
very convenient feature and is currently used by several customers that in 
production.

2. I am not opposed to having a pluggable external mechanism for configuring 
groups. However I am still not clear as to how these groups are tied to the 
authentication system. Bear in mind that the users in ACL are authenticated via 
our authentication mechanism. So any external mechanism used for the groups 
needs to be used in authentication as well. Could you pls clarify this point?

ADK: This is to allow other mechanisms, primarily directory services but also 
stand-alone group files, such as the unix /etc/group file. I have no problem 
keepin the ability to include groups in the ACL file, I would just like to have 
the ability to override this facility and use an external, pluggable mechanism. 
In many cases this will be separate from the authentication mechanism by their 
very nature - unix passwd and group is an obvious example, as is .htaccess and 
tomcat groups. We should continue discussion at QPID-2541 though.
