Installation ISsue

[Michele Catalano]

Hi

I'm trying to install kolab server on ubuntu 11.04. 
I get a famous error in installation but I don't understand solution proposed 
in internet...

ERROR : 

root at giacinto:/home/michele# sh install-kolab.sh

 Now running:

   /kolab/bin/openpkg build -kKBuZ -r "/tmp/install-kolab....26208" -p "ix86-
debian5.0-kolab" -D openldap::with_pth=no -D sasl::with_ldap -D

          openpkg-tools openldap postfix kolabd kolab-webadmin kolab-fbview 
kolab-webclient | sh

---------------------------------------
openpkg:build:FATAL: cannot open '/tmp/install-kolab....26208/00INDEX.rdf' 
(Permission denied)


I change permission to world readeable folder and files in tmp, but If I 
restart installation newer folder is created with permission restricted 
process. I know kolab user is involved in installation. In what I'm wrong?
