fix problems with encrypted data and NTLM login.

[leerlemoniii]

I made changes (discussed in #338) but did not write tests for this, since I do not know how these tests work, and am not very good at coffee script. In addition my time is limited, but I personally needed this change for my project.

Updated this pull request. All unit tests pass. Is there documentation on how to perform integration testing?
