Is there is any specific AD you want to integrate with. OOTB CQ comes with integration with LDAP which is pretty much plug and play with some custom configuration. Do you have any custom implementation requirement with this ? Also do want to integrate author or publish with your AD ?
In my project we are using LDAP Password for CQ login. Now we are try to login the system password as same to CQ also(System Windows Password). Do you have any Idea/Sample Implementation. Please share.
