Added more docs for find method in Group.pm Fixed a latent bug that would probably never occur in Macro/GroupAdd.pm If Group->find is called with the name of a group that doesn't exist, then Group will return an object with defaults, and the guid of the group is undef, not ''. However, since by default autoAdd is off, the Macro will still do the right thing. GroupDelete has the same bug, but it shouldn't be patched until there's a test written for it.

=head2 getIp ( )
|
|
|
|
Returns the user's real IP address. Normally this is REMOTE_ADDR, but if they go through a proxy server it might be in HTTP_X_FORWARDED_FOR. This method attempts to figure out what the most likely IP is for the user. Note that it's possible to spoof this and therefore shouldn't be used as your only security mechanism for validating a user.
