[horde] 1st time setup- test.php works, errors after that though (correction)

[Christopher Edmonds]

*** sorry horde version is 3.0.9, don't know where that 2.1.3 came  
from... ****

hi- long time J2EE developer trying to move to PHP (its easier  
right?) LOL

want to use horde as our groupware, and maybe develop some apps in it.

anyway, have a very basic linux box:

SuSE 10.0
apache httpd 2.2.0
mysql-5.0.18
php-5.1.1 with requested modules from PEAR etc
horde 2.13

setup everything per instructions in horde/docs/INSTALL, including  
inserting the appropriate tables into the DB with the supplied  
script, etc.

horde/test.php works fine, gives me a few interesting messages like:

(under PHP Version): Wow, a mystical version of PHP from the future...

I have "NO" for FTP Support, IMAP Support, Mcrypt support, OpenSSL  
support and PostgreSQL Support (using mysql anyway)

everything else is "YES" and the session counter works fine

what to do next though- in the INSTALL doc at step 5: Completing  
Configuration, things get murky

it talks about accessing Horde without a password, setting up auth  
backend, etc.- ok fine, but where to go to do that... no URL is  
provided, hmmm maybe just myhost/horde/ right?

ok do that, and am blessed with this:

in /usr/local/www/horde/lib/Horde/Perms.php on line 341

trying myhost/horde/admin i get:

 >Notice: Only variable references should be returned by reference  
in /usr/local/www/horde/lib/Horde/Perms.php on line 341
 >
 >Notice: Undefined index: log in /usr/local/www/horde/lib/Horde.php

I have spent a few hours making sure i have everything setup just  
right (i am a PHP newbie, but not to linux, or sysadmin stuff, or  
httpd config, etc) and either i am missing some very salient point in  
the install docs or something else is wrong

any help appreciated

also are there any other third party docs for horde, what i have  
found on the site seems kind of sparse (no offense)
