Windows Support
I recognize that Windows support is, um, limited :-) But, any ideas what exactly would need to be changed to support Windows (without cygwin) if someone such as myself were so motivated? The most immediate thing I ran into was the UserGroupInformation which would need a windows implementation. I see there is an issue to switch to JAAS too, which may be the proper fix? Are there lots of other things that would need to be changed? I think it may be worth opening a JIRA for windows support and creating some subtasks for the various issues, even if no one tackles them quite yet. Thanks, Dan -- Dan Diephouse http://netzooid.com/blog

Thanks, Dan I think a key one you need to address is motiviation. Is cygwin that bad for a piece of server-side code? No I guess I was trying to get an idea of how much work it was. It seems easy enough to supply a WindowsUserGroupInformation class (or a platform agnostic one). I wondered how many other things like this there were before I put together a patch. Seems bad Java practices to depend on shell utilities :-). Not very platform agnostic... Dan -- Dan Diephouse http://netzooid.com/blog
