Grouper Users - Open Discussion List

[Chris Hyzer <>]

Did we discuss this earlier when getting your hooks to work?  I forget.  IDs 
which are more friendly than UUIDs are nice to have, but there are issues 
when:

1. Sequences might get out of sync e.g. due to imports or db migrations, and 
start colliding with existing assignments

2. Imports in general, colliding with existing values.  Do you change the new 
one?  Break existing references?

3. Now you need an env qualifier to know you are referring to the right 
group: prod_123, or test_234

That is why Grouper would like to avoid that issue by using UUIDs for groups. 
 Just curious, why dont the existing UUIDs work for you?

Thanks,
Chris
