The presence of OpenSSL is determined at ./configure time. Please check that ./configure actually found SSL library and headers if you install Polygraph and want SSL support:

The exact messages may have change, but they are still there:

  $ ./configure | grep -i ssl
  checking for SSL_connect in -lssl... yes
  checking openssl/ssl.h usability... yes
  checking openssl/ssl.h presence... yes
  checking for openssl/ssl.h... yes
  checking openssl/err.h usability... yes
  checking openssl/err.h presence... yes
  checking for openssl/err.h... yes
  checking openssl/rand.h usability... yes
  checking openssl/rand.h presence... yes
  checking for openssl/rand.h... yes

Assertion at NtlmAuth.cc:798 means that you built without OpenSSL
support.  You should install it and rebuild.  On Debian-based systems
you should install libssl-dev package.

The assertion is always a bug.  Web Polygraph should print a proper
error here.  There is an open bug #878881 [1] for this issue.

NTLM needs some crypto functions (MD5, at least).  That is why OpenSSL
is needed for it.

But I'm not sure if polygraph was compiled with or without SSL. Is there a way to test it? Or what do I have to do to make sure that polygraph compiles with SSL support?
