The release of Rubygems 0.9.2 (and possibly earlier) introduced an  
incompatibility with the patch supplied with RubySSPI. The newest  
releases  
fixes that incompatibility.

This release does, however, introduce new class and module names and is  
not  
backwards compatible with previous versions of the library. If any code  
has  
been developed against the gem, be careful when upgrading.

# What is it?

This library provides bindings to the Win32 SSPI libraries, which  
implement various security protocols for Windows. The library was  
primarily developed to give Negotiate/NTLM proxy authentication  
abilities to Net::HTTP (and thus, open-uri), similar to support found  
in Internet Explorer or Firefox.

The library is NOT an implementation of the NTLM protocol, and does  
not give the ability to authenticate as any given user. It is able to  
authenticate with a proxy server as the current user. It also does not  
provide full bindings to the SSPI library, but could be extended in  
that direction if anyone is so inclined. Someone recently mentioned  
the idea of extending it to allow NTLM authentication with SQL server  
(removing the need for usernames or passwords in configuration files).

# What does it do for me?

If you are behind a proxy that authenticates all traffic, then this  
library will enable your ruby scripts to authenticate with the proxy  
as the current user. This solves the shortcomings of other solutions  
(such as Basic authentication or the python APS proxy[1]) which  
require you to enter your username and password in clear text at least  
once.

It also enables scripts such as the “gem” commands to work without  
special hacking. Methods of enabling these scripts are described in  
the accompanying documentation.

# Where is it?

# How do I install it?

gem install rubysspi

Once the gem is installed, view the RDoc documenation for complete  
instructions on using the library.

# Anything else?

Please use the forums on the project page for bug reports, support  
requests, etc. Enjoy the library!

[1] A proxy, implemented in python, which handles NTLM authentication  
for you. It is implemented as a proxy-proxy, meaning you run it  
locally and point all web traffic at it. It does require you enter  
your username and password to work - it does not authenticate as the  
“current” user. [http://ntlmaps.sourceforge.net/](http://ntlmaps.sourceforge.net/)
