Single Sign-On with Microsoft NT LAN Manager SSP: NTLM v1 or NTLM v2 ?


After reading lots of documentation and SAP notes, I am not able to find this simple information :

Which release of NTLM protocol does Single Sign-On for sapgui with Microsoft NTLM use : v1 or v2 ?

We do use successfully NTLM for sapgui direct access with GSSNTLM.DLL and GX64NTLM.DLL for 1500+ users.

Our current domain controllers are running Windows 2003 and will soon be upgraded to Windows 2008R2. As part of this migration, the domain admins told us that NTLM v1 will be deactivated because considered obsolete and not secure enough.

So, if GSSNTLM.DLL is not able to use NTLM v2, we are in trouble !
