[chef] Nested Databags

[jfotop < >]

Hi!!

I'm new to chef and liking it so far. I have a simple question (could be even
called stupid): Could I create a nested databag to create a structure like the
following? :

access_groups = { Developers => {  Tim => 10.0.0.1, Brandon=> 10.0.0.2 },
                  Admins =>     {  Jacob => 10.1.0.1, Curtis => 10.1.0.2, Mary
=> 10.1.0.3},
                  Sales =>      {  Rebecca => 10.3.0.1, George => 10.3.2.1} }

in one databag?
Use case:
When a node is created, it would set an attribute which is an ldap_group (or
maybe 2 or 3 ldap groups). The ldap_group names correspond to the group names
above. So when I want to configure iptables, I will have to loop over all
specified groups and get every IP from the users in the group(s). I also want
the usernames, because each user in that group will be added to a local group,
in order to grant him sudo access to different stuff. 

Any other ideas on how to accomplish this would be appreciated.
