[horde] Progress with "You must configure a Category backend to use Horde." error

[Shane Boulter]

Ok I've been reading the mailing list's regarding this error message and 
I've gotten about as far as everyone else having this problem.  I did 
however find out where and why the message is happening. I just don't 
have enough php programming experience to fix it.

In the file Perms.php on line 49 there is an if statement to check if a 
category driver has been set.  Even though it's been declared in the 
conf.php file it always returns blank.  If I comment out the check and 
hard code the $driver to be 'sql' on line 53 I will get a different 
error about not being able to read another $conf['blah']['blah'] 
parameter.  So obviously I'm not able to read any of the configuration 
parameters.

If the HEAD release is working for some people then it seems to me to be 
  possibly a php setting that is different.  Just like the other's 
though the test.php says that everything is fine.

Here is a quick list of my machine specs:

Redhat 7.3
Apache 2.0.48
php 4.3.1


Hopefully someone with some more knowledge about the inner workings on 
Horde and/or PHP can shed some more light on this.
