Jacques,
When you have a few minutes, please take a look at https://issues.apache.org/jira/browse/OFBIZ-1349
- that should eliminate any future confusion.

Thanks to Jacopo for having catched it and, to all participants for the
explanations I got from this thread !

The current SVN is doing an AND on the base-permission list.
To recap: I added the ADMIN permission check to the main application bar logic.
When I did that I
also changed the logic to OR the base-permission list - based upon my
misunderstanding of the usage
of the base-permission list. Jacopo caught that and changed it back to ANDing
the base-permission list.
At any rate, the discussion has been informative. David - thanks again for your
input!

I haven't reviewed the patch, but just to make sure we're all on the
same page: it is doing an AND, right?
In other words it requires all permissions in the list, not allowing
just any?
Personally I don't think either AND or OR is implied by the attribute
or it's usage, just a matter of what is most useful and then perhaps
documenting it with an annotation in the XSD file or something, and I
think based on the discussions I remember (I don't remember who
implemented that though, perhaps Andrew Z.) we decided AND would be
more useful.

Yes, your patch is correct. Thanks for catching that!

So, at the end of the story... is my last patch correct, right?
Sorry, but I'm a bit tired today and I'm getting a bit dumb.

David,
Thanks for your input!
Si makes a good point about permissions that have unexpected side-
effects. Let's say you're using some of the Party Manager screens
in a custom app. Inside those screens are permission checks for the
PARTYMGR_VIEW permission, so you give that permission to your
custom app users. Oops, now they have access to the Party Manager
application. By ANDing the base-permission list, if they don't have
the OFBTOOLS permission, then the Party Manager application doesn't
appear.
The OFBTOOLS permission idea solves the problem. It just seems
counter-intuitive in the base-permission list.

Not sure where Si got his notes, but I think what you are writing
is correct Adrian.
If I remember right from the initial discussions around this the
point was to be able to add on other applications and have more
control over which a user can see, the common scenario being that
you would want to be able to setup a user that could see the
add-on application (even though it does have a security
permission), but not the base ofbiz applications. With that you
could just not include the OFBTOOLS permission in your add-on
application and off you go...

Jacopo,
Doing a Google search, I found these notes from Si:
http://www.opensourcestrategies.com/ofbiz/security.php
According to Si, the list of base permissions should be ANDed,
not ORed. I don't know the reasoning for that, however.

Adrian,
I think that you could be right.
I'm not sure I understand the meaning of the OFBTOOLS
permission, but I don't think it was intended as the base
permission for the Webtools application... but I could be wrong.
Any hints from others?

Jacopo,
How was the original logic incorrect? The original logic was this:
For each application:
Permission to use the application defaults to false
If the user has one of the permissions in the application's
base-permission list,
OR if the base-permission list contains "NONE", then
permission to use
the application is true
The reason all of the applications became visible to a user
with the OFBTOOLS permission is because all of the
applications have the OFBTOOLS permission in their base-
permission list.
My understanding is that the OFBTOOLS permission was intended
to grant access to the Webtools application. I don't know why
it has been included in every other application.
