[imp] Imp open_basedir problem

[woj woj]

Hello,
When I turn on openbase_dir i got errors in horde log file:

[imp] PHP ERROR: curl_setopt(): CURLOPT_FOLLOWLOCATION cannot be activated
when safe_mode is enabled or an open_basedir is set

My open_basedir:
"/usr/share/php:/var/lib/php:/etc/resolv.conf:/var/www/html/horde:/usr/share/pear:/tmp:/etc/ssl/certs/"


CURLOPT_FOLLOWLOCATION  function is critical ? I should turn off
open_basedir or ignore this errors ?
