OpenLDAP and AD integration

Hi Friends,

I am newbee to this community and want to know how I can integrate an OpenLdap Server with MS Active Directory. Such that I create a user in LDAP it reflects in AD as well and vice-a-versa. Similarly any changes should effect on both AD and LDAP. Also I want to know how this can be done with a technical documentation. Also a user incase AD is not available gets authenticated using LDAP and vice-a-versa.

Your urgent help on this issue will be highly appreciated. Expecting a reply from you at the earliest.

Thanks and Regards Santosh Balan +91-9819419509
