Hello,
I am using default keystone installation on Grizzly, I guess it is sql backed. I want to get openstack users to get from Active Directory server with LDAP integration. Can I do it without changing sevice users? I have nova glance etc users, do I need to migrate them to active directory?
You need to create the service users in LDAP. As of now that is the only way to do it. There are other options which are not that trivial
1) Wait for Juno, where keystone is going to support a backend per domain. So you can have all your service users in SQL and other users in LDAp
2) Write your own middleware and insert in the keystone piple line. Default keystone is configured to use ldap. Your middleware will do user lookup in sql only for service user, for other users keystone ldap driver will do . (ie). If auth fails from configured ldap dirver, check if the user is service user and if so authenticate them using sql backend
Take a look at these links on how to accomplish this. Basically you have to setup LDAP or AD for Openstack then modify the keystone.conf file.

My main question is that how can I integrate glance, nova, quantum users in the default Keystone to AD backed Keystone? I guess service users will not be able to connect to the keystone; therefore, services will not be available until I create those users in the AD; am I right?
You'll have to add the users in AD if you change the backend for keystone to LDAP. The users need to exist where Keystone is looking for users.
I'd recommend looking into assignment + identity in keystone, it was introduced in Havana. It makes the whole setup process 100 times easier. The most frustrating/difficult part of setting up AD for keystone in Grizzly is getting the roles and tenants configured correctly. You could skip the frustration by using SQL for assignment (Roles, Projects) and LDAP for identity (Users, Groups.) In this case you would still need to add the service users to AD.
