Ok, so i changed the value for timezone lookup in the Horde  
configuration to  
http://www.iana.org/time-zones/repository/releases/tzdata2013c.tar.gz  
because http is available by proxy. But the webserver still try to  
access the IANA site by FTP?
A file URL doesn't work either. Is this the rigth place or do i have  
to change something else? Any pointer how to solve this are appreciated.

Regards

Andreas
