This Week in OpenNMS: Season 1.6, Episode 16: ACLs: The New Hotness

It's time for This Week in OpenNMS.  In the last week we got a basic
working ACL implementation, as well as some other updates.


Project Updates
---------------

- Stable: Current Release is 1.6.4

1.6.4 is the current stable release, released (no kidding!) April 1st.
It fixes a number of bugs, and adds a few features.  For a full list,
see the bugzilla 1.6.3 and 1.6.4 milestones.  This is a recommended
upgrade for anyone on OpenNMS versions older than 1.6.4.

- Unstable: Current Release is 1.7.2

1.7.2 is the current unstable release, released alongside 1.6.4 on April
1st as well.  It fixes a whole raft of bugs since 1.7.0, and barring
still not handling newSuspect events, Provisiond is pretty solid.  A
1.7.x overview is available in the release notes on the site.

- Trunk: ACL First Draft (+Hibernate Updates)

A first working draft of the new ACL support is in-place as of this
weekend.  As part of this work, we've upgraded to the latest Hibernate
and related tools.  We'll be fine-tuning it this week, and will
hopefully have a 1.7.3 release out sometime this week so people can kick
the tires.

- Trunk: RANCID Updates

Some minor tweaks and cleanups were integrated into the RANCID web
service. The RWS is now approaching a release version, and 0.92 is now
available for download.

- Trunk: WMI Updates

Some socket leaks in the WMI code were fixed, and Matt Raykowski also
did some work cleaning up the CheckWmi command.


ACLs in Trunk
-------------

We finally have a long-requested feature implemented in trunk: being
able to limit which devices/interfaces/etc. a user sees based on a
certain criteria.

If you want to give ACLs a try, here's what you need to do:

1. Enable ACLs

   You can do this by editing "$OPENNMS_HOME/etc/opennms.properties" and
   uncommenting/enabling the ACL line so it says,
   "org.opennms.web.aclsEnabled=true".

2. Create a User

   In the admin UI, go to "Configure Users, Groups and Roles", create a
   user in "Configure Users", and then go back to "Configure Groups",
   create a group, and put the user in that group.  Also, make sure you
   have one or more node categories assigned to that group.  That will
   map the user to the nodes he is allowed to interact with.

3. Assign Nodes to Node Categories

  To manually put nodes in a particular category, you can use the
  "Manage Surveillance Categories" to add nodes to the category, or
  assign them automatically using the NodeCategorySettingPolicy ("Set
  Node Category" policy) in the new provisiond config.

Once you log in as that user, you should see only the nodes in the
categories assigned to that user's group. This is still very early code,
so if you find issues, please open a bug, we really want to work out the
kinks.
