Need script to check LDAPS

I have 110 Domain controllers in my environment. The Platform consists of Windows 2003 Server SP2,Windows 2003 Server x64 SP2, Windows Server 2008.
All the servers are supposed to have certificate installed on them and running on LDAPS.

I need a script which could connect on every server at port636, verify that server is running LDAPS and also connect to its cert store and get the Certificate expiry date.

Guys Please help me with this.
