[1.4.2] Permissions history/Graph

[NOB]

Hi

I have two systems set up:

ONE is a stand-alone system
TWO is a slave system (with no master, yet) and NodeID = 5

So, what's the difference ?

Here it goes:

I have a user group with read-only access to one hostgroup.
Everything is fine, except the following:

If a user in this user group accesses "Latest Data" for a certain host,
the data shows up.
On ONE (NodeID = 0) he can select "Graph" and the graph shows up.
On TWO (NodeID = 5) he can select "Graph" but the result is "No Permission".

Debugging shows that the list of "denyed_hosts" on TWO contains - more
or less - all hosts, while the "availiable_hosts" array contains only
those, which are permitted.
So I change the history.php to check for "not in ($availiable_hosts)" and
now it works as advertised

See patch in attached file.

The real problem seems to be in perm.inc.php but I didn't debug this, yet.

Regards

Norbert.
