Anyone know if the Notes 8.0.1 client that uses SSO windows service "Lotus Notes Single Logon" is using SPNEGO, Kerberos, or ngina.dll?

Subject: Since 6.0

Since 6.0, NSL uses the Windows Network Provider interface.

more specifically the NSL Network Provider (npnotes) is a Credential Manager:

which uses password sychronization between OS and the Notes ID to simulate single logon. The NSL service brokers the password between the OS and the Notes client.

Pre-6.0 used GINA. Future releases are moving away from the NP technology (and password synchronization in general)
