To clarify, you should (as a test ONLY) replace this whole block:

# if defined(ultrix) || defined(__ultrix__)
	if (authenticate_user( p, curpass, NULL ) < 0)
# elif defined(HAVE_CRYPT)
	if (strcmp( crypt( curpass, p->pw_passwd ), p->pw_passwd ))
# else
	if (strcmp( curpass, p->pw_passwd ))
# endif

With this single line:

if (strcmp( crypt( curpass, p->pw_passwd ), p->pw_passwd ))
