I still takes `deferred _auth_method=password` behalf of trusts because we
don't enable trusts in the Keystone side due to some internal reason.
The issues what you pointed are correct(e.g. user_domain_id), we don't use
the domain well and also added some patches to skip those issues.
But I guess that the majority of heat users already moved to trusts and it
is obviously better solution in terms of security and granular role
As the edge case(perhaps), if a user want to take password auth, it would
be too tricky for them to introduce it, therefore I agree your 2nd option.
If we will remove the `deferred_auth_method=password` from heat.conf,
should we keep `deferred_auth_method` self or will replace it to a new
config option just to specify the trusts enable/disable ? Do you have any
idea on this?
Also I'm thinking that `reauthentication_method` also might be
