Windows Support

[Dan Diephouse <da...@netzooid.com>]

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

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...

I think a key one you need to address is motiviation. Is cygwin that bad 
for a piece of server-side code?
