This was discussed with Colleen and Kristi in IRC [0]. The following was
proposed

 - write a patch so that devstack always configures sql as the identity backend
 - when ldap is set as KEYSTONE_IDENTITY_BACKEND, ensure it's done in a domain-specific way
 - write a patch so keystone fails gracefully with an informative warning saying `bootstrap` is only intended for sql-based deployments

Thoughts on the approach?

Title:
  bootstrapping keystone failed when LDAP backend is in use

Status in devstack:
  In Progress
Status in OpenStack Identity (keystone):
  Triaged

Bug description:
  "keystone-manage bootstrap" command is coded for SQL backend, it's
  should be okay if admin token is always supported by keystone, but we
  have a plan to remove the support of admin token since it's expose a
  security risk. And the patch to remove the support of write operation
  for LDAP backend is on the fly.

  Based on the above consideration, we should enable the bootrapping
  keystone when using LDAP backend, but it currently not work sometimes,
  for example.

  
  # keystone-manage bootstrap --bootstrap-username Dave --bootstrap-password abc123 --bootstrap-project-name admin --bootstrap-role-name admin
