  Test generation could abusively skip some web service calls
  and answers. No specific error would appear in the Error
  Log.
  
  This anomaly would typically occur with web service calls
  with NTLM authentication respecting the following format :
     Authentication:  Negotiate
  ?NTLMSPP_SOME_CONTENT_ENCODED_IN_BASE64?"
  
  Previously on, recognized HTTP header for handling NTLM
  authentication was
  " Authentication:  NTLM
  ?NTLMSPP_SOME_CONTENT_ENCODED_IN_BASE64?".
  
  Now, the following additional format is also handled :
  " Authentication:  Negotiate
  ?NTLMSPP_SOME_CONTENT_ENCODED_IN_BASE64?"
  

Problem conclusion

• Fixed by verifying the first bytes of the Base64 string are
  "NTLMSPP".
  

Temporary fix
