[horde] problem with datatree

[Chris]

Hello everyone.

I have horde 3.0.9 working.  I am having some difficulty, as I am not
finding much documentation on horde out there.  For now, I have it
working with .htpasswd, but I would like to change that at a later date
so that I can use groups and users (I am, however, at a loss on how that
works...).

I am using mysql as a backend, on openbsd 3.8.  I have nag
(nag-h3-2.0.4) configured, and it almost works, but I am experiencing
some bizzarre behavior.  I think it is related to the datatree system
configuration.

My question:

On the admin interface, when I configure the datatree system, there is a
field that says:
"The name of the data table in the database [horde_datatree] ".  What am
I supposed to put in this field for nag to work properly?

If I leave it blank, or put in "horde_datatree" nag allows me to create
new tasks, but it will not let me view them (always says 0 tasks, even
though it says it successfully saved them).

If I put something in this field besides "horde_datatree", I can see the
tasks I saved, but it will not let me view or access them in any way! 
It gives me an error stating I don't have permission: "Error  You do not
have permission to view this tasklist."  The add a task icon isn't even
present on the toolbar.

For the life of me, I cannot figure out what I did wrong here...

When installing horde, I did use the
scripts/sql/horde_datatree.mysql.sql script.

Can someone please help?

Thank you.

Chris
