Description of problem:
We have provided the feature of integration of keystone with LDAP/AD as an external back-end since OSP7. , , , 
This feature works well when the customers configured their Stack system manually.
But after integration, updating overcloud nodes via Director failed.
Since many customers are interested in this integration and they would like to make it via Director, it's very important for us to make it possible via Director.
It seems to me that OSP8 does not have this feature (maybe OSP9 as well?).
It would be better to let the customers know when this feature will come out officially.

This feature is expected to land in OSP12. Closing this as a duplicate of the OSP12 RFE bug.
