We recently setup ADFS as part of our implementation of Office 365.  In setting up ADFS to authenticate to a second service we subscribe to, we were told by the vendor that our ADFS servers need to support SSL 3.  

Being new to ADFS, I took to the web put I am unable to find any documentation on how to do this.  I have tried the registry edit to enable SSL 3.0 for IIS that I found, but the ssl test site the vendor is using is still showing that it isn't enabled.

Any suggestions?

Take a look at disabling V2 then you should be able to pass their test for V3

SSL v2 is weak and outdated protocol. All modern browsers support SSL v3 and it's enabled by default on Windows 2008 (IIS 7 / IIS 7.5). To make sure all clients are using SSL v3 we must disable SSL v2. This is required for PCI compliance.

This is what needs to be done to disable SSL v2:

1. Start - Run
2. Type "regedit" and click OK
3. Locate the following key: HKey_Local_Machine\System\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\SSL 2.0
4. Right click the "SSL 2.0" key and select Edit > Add key
5. Type "Server" and click Enter
6. Right click Server and select New > Add DWORD (32 bit) value
7. Type "Enabled" as the name and make sure the value is "0"
8. Restart the server
