Open Stack

Hi,


Apologies if this questions has been answered already, or is in some doc
somewhere. Please point me in the right direction of so.


I'm upgrading openstack from Juno to Mitaka, in steps.  We role our own
openstack using puppet, and have been using identity v3 in Juno with
domains via an ldap backend.

The upgrade process is largely created, tested and working, but not rolled
out across our production sites yet.

However, I notice when I create a new cloud using openstack Mitaka from
scratch, not upgraded from Juno, the _member_ role is no longer created
automatically when users are assigned to projects [ tenants in old money
].  I'm pretty sure this was happening in Juno, and the Juno docs seem to
confirm it.
I believe horizon at least was using this role to allow users access.

I've noticed this because we have scripts to automate some user/group
stuff, and the have some usage of the _member_ role hard coded atm.  They
are failing, as the role doesn't exist on non-upgraded clouds :)


So I would like some advice/clarification on what the situation is.

What else, if anything, was the _member_ role used for? heat maybe?

Is the _member_ role no longer required at all, not even by horizon?

If it's no longer required, is it safe or desirable to remove the _member_
role from upgraded clouds?





Cheers,
Just
