Public bug reported:
When keystone is configured with ldap server as identity backend, if incorrect
credentials were configured under [ldap] section [1] of domains conf file, then
POST request on /v3/auth/tokens API with users in ldap is returning unexpected
500 error [0] with stacktrace[2] shown below.
Instead of unexpected error user should be given a proper message about invalid
credentials configured.

your request.", "code": 500, "title": "Internal Server Error"}}
