Syncrepl multi-master

Dear All, I think I know very little about LDAP. Was struggling to configure it for the underlying configuration. Was just wondering if anyone could help me in this regard as I'm running out of time already.

I wanted to configure it for two LDAP masters (I mostly see 3 everywhere on web, I tried to correlate and implement for 2 but for no avail). May be I'm going wrong somewhere. As of now using a java stand alone program to write (can also be read is "create") records to one LDAP master (read Master 1). And use LDAP browser to verify the data being altered. I did try to configure it but luck didn't favor. My hunch was the data being modified in Master 1 should reflect to Master 2 in exact. But it doesn't seem to work, was puzzled where I might have gone wrong. Please someone also guide me on where/how can I see logs for the same in UNIX(learning to work on unix system) system if they can be helpful. Would be grateful if someone could really point out my mistake or in my very understanding. Thanking you in advance and awaiting a response. Here follow the details fyi,

Also if I'm done with this I would like to know what the server will understand by each term used here in slapd.conf. Kindly point me where I can find the anatomy of slapd.conf file if you know. Thanks again!
