Sorry, I hit send by accident before I was done.
Hi Eric, et. al.,
I think this question boils down to what's the best way to
enforce a single namespace for group aliases. You can
search for a group by name, but as we know, unique names are
not required or enforced. Or you can declaratively alias a
group or groups to a particular symbolic name. In the
composite group service bean in spun-off gap there is a Map
of symbolic names and their related group keys:
<!--
| Declare DISTINGUISHED GROUP KEYs here.
| These are simply aliases for group keys
| that are known to the group service. (A
| single group can have more than one
| alias.) At runtime, a distinguished group
| can be retrieved from the service
| using getDistinguishedGroup(String name).
| Note that in the Map defined below,
| the entry key is the ALIAS and the entry
| value is the GROUP KEY.
-->
<property name="distinguishedGroupKeys">
<map>
<entry key="Everyone">
<value>local.0</value>
</entry>
<entry key="Everyone-Redux">
<value>local.0</value>
</entry>
<entry key="Students">
<value>local.1</value>
</entry>
</map>
</property>
These symbolic (or "DISTINGUISHED") names are different from
the names returned by IEntityGroup.getName().
If it makes sense, we could backport something like this to
earlier versions of GaP in uPortal.

Thanks for the update. I have a few ideas for getting rid of the
explicit configuration tie to the synthetic group IDs.
1. Switch to just using well known names. An example would be "All
uPortal Users" for everyone, "All uPortal Channels" for all channels and
"uPortal Administrators" for admins. Some effort would need to be done
in the composite group store to prevent these groups from being created
by users for security reasons which may be a bit of a road block.
2. Move the config into the database. A table could contain a known real
id and the corresponding synthetic id of the designated group. This
information could more easily be exported and would reduce the
configuration tie to specific group keys.
Thoughts from any devs out there?

Eric,
I updated dbunload,crn per our discussion on IRC:
http://developer.ja-sig.org/source/changelog/jasigsvn/?cs=43464
It still needs some attention, though...
There are 3 rows defined in the UP_GROUP.default-data.xml file, each
of which refers to an EntityType by Id: IPerson or IChannel. We
either need to include a .default-data.xml file that defines these
dependencies, or remove the need for 'Everyone', 'Portal
Administrators', and 'All Channels' to have specific Ids.
