Comment 9 for bug 1582729

We have deployed Openstack Train Version using kolla-ansible(9.3.1)

After adding AD server configuration details in the keystone.conf where the path as /etc/kolla/keystone/keystone.conf.

I referred to this link for setting up AD DS server on keystone identity container-->
https://wiki.openstack.org/wiki/HowtoIntegrateKeystonewithAD

Outcome:
Need to integrate keystone identity service with AD DS server.

Below is the issue when we restart the container of keystone identity service:
