LDAPS and Server 2008 R2

Read a lot about this on this site and others but still have a few questions if someone can help.

My client has a cloud antispam/antivirus service that performs directory harvesting via LDAP into their AD.  Need to secure this with LDAPS.  They do support it.

1.  Want to use a GoDaddy SSL.
     a.  I assume standard SSL will work?
     b.  Already have a UCC for Exchange 2010
2.  Do I create the request via IIS like usual or via the AD certificate services?
3.  Where does the "Server Authentication object identifier" get inserted into the SSL?
      a.  all the articles stress that the cert has to perform this function compared to the "identity of a remote computer" role in the Exchange SSL.

We tried to self sign it and using the recommendation of not putting the CA on the domain controller itself, we could never get the "security" correct to choose the template we created and were trying to issue per this article - http://social.technet.microsoft.com/wiki/contents/articles/2980.ldap-over-ssl-ldaps-certificate.aspx

And when we use a GoDaddy SSL, do we still need to do the request.inf - http://support.microsoft.com/kb/321051  - why is this different to a normal SSL request?


 I guess we need a little clearer step by step.  Any help is appreciated...

You DO NOT have to buy a cert to use, it add's nothing to security of the process technically, since the ldap service will not check for a revocation certificate, which is all adding a paid for cert would be able to possibly add. It's SSL encryption but not the entire protocol, like where it checks for revocation before establishing connections.
As long as you're importing the self-signed cert, it should work, it's pretty easy.
http://support.microsoft.com/kb/321051 (yes you need the INF)

Thank you.  
Although the article does not specify, a couple more questions?

1. Do I need to have AD Cert services installed on the DC that will trust the cert?
2. I assume I can use IIS on one of my other servers to create the self signed cert?
3. In the KB, it shows win2k8 improvements, do I need to load cert into the NTDS Service's Personal store or just machine's ps?

I really appreciate the help!

Thanks

1= No, the cert stores are on every machine by default.
2= IIS can I believe, I use openssl however:  http://www.openssl.org/related/binaries.html + http://social.technet.microsoft.com/Forums/windowsserver/en-US/126c3644-3632-407b-a850-72be82766849/ldap-over-ssl-windows-server-2000-vs-windows-server-2008
You do have to manually distribute the cert when you don't have a CA though.
3= Personal store only for connecting machines.

Thank you again.   This gets me pointed into the correct direction and understanding.  Openssl  seems a bit complicated to me versus the IIS method.  Used to doing IIS in the early days with OWA on Exchange 2003 with self signed certs.  Will give them a try.

Thanks again.
