Bug description:
  When using an LDAP domain user on a bionic-rocky cloud within horizon,
  we are unable to see the projects listed in the project selection
  drop-down, and are unable to query resources from any projects to
  which we are assigned the role Member.

  It appears that the following log entries in keystone may be helpful
  to troubleshooting this issue:
