Dear All, I am extrmly new to this OpenLDAP world. I wish to know Can I query OpenLDAP using ADSI? My requirement is just to authenticate, whether user exisst or not. The input will be server name, domain name, user name and password. Optionally the input may also include ounit and port also. I also wish to query using SSL or TSL. Nice examples could really help me. Thanks in advance. Regards Pravin Joshi
