[horde] Preferences Problem

[Kai]

Hello all,
i have just installed Horde, Imp, Kronolith, Turba, etc. from the
latest snaps.

It all runs just fine until the point i set $conf['prefs']['driver']
in the horde/config/conf.php from 'none' to 'sql'.

The next time i log in i get the following 3 warnings:

  Warning: _connect() [function.-connect]: open_basedir restriction in effect.
  File(./DB.php) is not within the allowed path(s): (/home/www/web2/) in /home/www/web2/html/horde/lib/Prefs/sql.php on line 454

  Warning: _connect(DB.php) [function.-connect]: failed to create stream:
  Die Operation ist nicht erlaubt in /home/www/web2/html/horde/lib/Prefs/sql.php on line 454

  Fatal error: _connect() [function.-connect]:
  Failed opening required 'DB.php' (include_path='.:/usr/share/php') in /home/www/web2/html/horde/lib/Prefs/sql.php on line 454

open_basedir restriction is active, but configured correctly (it works
perfect without the preferences option)

the sql.php line 454 tries to require_once the DB.php.

makes no sence to me.

appreciate any help.

sincerly yours
