Morgan, Gilles and I spoke about this on IRC. I think we agreed that
making the columns in the trust database have a unique constraint is the
way to go. So if two requests came to create trusts with the same
trustor/trustee/roles/expiration/scope/impersonation, then the second
would bring up an exception saying there's a conflict.

Title:
  Missing name field for trusts

Status in Keystone:
  Triaged

Bug description:
  A name field in Keystone DB is needed for helping identifying trusts.

  Effectively , there could be multiple trusts for a same
  project/trustor/trustee including the same expiry date and same
  impersonate flag. And the same combination could have multiple trusts
  assigned with different roles or not.

  Having a name would help for implementing trust usage.

  A use case scenario is currently with Puppet Keystone module while
  creating the trust provider:

  When creating a resource, Puppet uses a name as a title for the
  resource, that name is unique in order to provide idem-potency. The
  trust ID (Keystone DB) doesn't exist until its creation and therefore
  cannot be used as a title for a Puppet resource. Without a name,
  puppet provider has to make up a name from the different fields, which
  doesn't guarantee uniqueness anyway. Worse when fetching resources,
  the provider would have to fetch all the fields to identify the
  resource and take the first one if many available.

  So far, most other Keystone DBMS objects (tables) have a name, which Puppet has been able to use to identify resources.
  The latter is why it made more sense to create this request as a bug instead of a blueprint, basically saying a name has been missing upfront rather than being a request for enhancement.
