Description of problem:

Customer has found the OSP12 Active Directory integration documentation is missing some potential steps. 

Document: https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/12/html/integrate_with_identity_service/sec-active-directory


Note: I have no access to a AD environment to verify.


Version-Release number of selected component (if applicable):


How reproducible:
- Unknown as no active directory environment to test with. Assuming always.


Steps to Reproduce:
1. Follow: https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/12/html/integrate_with_identity_service/sec-active-directory
2. Test integration

Actual results:
- Integration fails


Expected results:
- Integration works.


Additional info:
- Customer supplied the following snippets that seemed to have resolved his issue:
########### START ###########
...
1.8.2. Configure the controller
...
2. Create the domains directory:

# mkdir /var/lib/config-data/puppet-generated/keystone/etc/keystone/domains/
# chown 42425 /var/lib/config-data/puppet-generated/keystone/etc/keystone/domains/
...
3. Configure Identity Service to use multiple back ends:

NOTE
You might need to install crudini using yum install crudini.

# crudini --set /var/lib/config-data/puppet-generated/keystone/etc/keystone/keystone.conf identity domain_specific_drivers_enabled true
# crudini --set /var/lib/config-data/puppet-generated/keystone/etc/keystone/keystone.conf identity domain_config_dir /etc/keystone/domains
# crudini --set /var/lib/config-data/puppet-generated/keystone/etc/keystone/keystone.conf assignment driver sql

...

6. Change ownership of the configuration file to the keystone user:

# chown 42425 /var/lib/config-data/puppet-generated/keystone/etc/keystone/domains/keystone.LAB.conf
...
_______

Also there is a crudini that points to the wrong file

3. Configure Identity Service to use multiple back ends:

NOTE
You might need to install crudini using yum install crudini.

# crudini --set /var/lib/config-data/puppet-generated/keystone/etc/keystone/keystone.conf identity domain_specific_drivers_enabled true
# crudini --set /var/lib/config-data/puppet-generated/keystone/etc/keystone/keystone.conf identity domain_config_dir /var/lib/config-data/puppet-generated/keystone/etc/keystone/domains
# crudini --set /var/lib/config-data/puppet-generated/keystone/etc/keystone/keystone.conf assignment driver sql
