The function you are looking for is in
[bin/default/]librpc/gen_ndr/ndr_ntlmssp.c

In source4/librpc/wscript_build you can find:

bld.SAMBA_SUBSYSTEM('NDR_NTLMSSP',
source='../../librpc/ndr/ndr_ntlmssp.c ../../librpc/gen_ndr/ndr_ntlmssp.c',
	public_deps='LIBNDR NDR_STANDARD'
	)

That means that you need to modify the deps of NTLMSSP to include
NDR_NTLMSSP.  See source4/auth/ntlmssp/wscript_build and extend 'deps'
to be: deps='MSRPC_PARSE CREDENTIALS NDR_NTLMSSP',

That should do it.

Normally the wscript_build file for a subsystem is next to the C files
for that subsystem.  Currently there is an exception for the shared IDL.
I'll see about correcting that next week, as kai's waf build should use
the same files.

I hope this helps,

Andrew Bartlett
