Which is why you can't use them together.  Use one or the other, not both.

There is not intended to be multiple units doing the same thing.  One unit
is older, the other is newer.  I do not know which one is meant to be used
for NTLM, as I don't use any of the IdAuthnetication classes myself.  I'm
guessing IdAuthenticationNTLM, since that is what IdAllAutnetications uses.
The main difference between the two is that TIdAuthenticationSSPI uses
Microsoft's own security API, whereas IdAuthenticationNTLM implements NTLM
manually instead.
