What's Wrong With Utux-Utux?

Learning LDAP can be a frustrating experience. LDAP is complicated, and centralized authentication is only one of its many legitimate uses. As a result, the task of making Linux machines consult an LDAP server for authentication is a black art. Documentation tends to be spotty and confusing. But learning about LDAP authentication, despite its difficulty, is worth the time and effort. LDAP can provide a scalable and secure approach to network management.
I've failed to practise it with both of Fedora (or Centos, i've forgotten) and Suse. But Mr Sumodirjo told me to try ClarkConnect. It has been installed and set up there. So you just only do simple way to create user, configure the samba and anything else related to.
You can get it here.

Fuh.. After installing OpenSuse 11 at my computer now I had to HP LaserJet 1020 printer driver installed. First download the driver at sourceforge. It seems OK since all of HP printer tipes could be detected with this hplip diver. But now I got a new problem how to install run file I've had.
It's said that You just run it like common script. So I tried this command
./hplip-2.8.6.run
But... Why it doesn't work???
I thought a little bit and..
Upszz... I've forgotte to do this one before =P.
chmod +x hplip-2.8.6.run
