I'm struggling trying to configure Keystone with AD support. Since the documentation of suse-cloud 4 is very short I ask here for advice.
I already tried to edit the configuration in Crowbar/Keystone and deployed it without success. My goal is to setup a read-only AD for Keystone.

"identity": {
"driver": "keystone.identity.backends.ldap.Identity"

"assignment": {
"driver": "keystone.assignment.backends.sql.Assignment"

In the LDAP section I edit everything that it seems to be needed. But after applying the changes I get an error starting with

Failed to talk to keystone in add_user

Is there further documentation from the side of SUSE? Could you please provide some advice?
