Yippie, thank you Stefano
The steps I followed to solve the problem:
1) for f in $(rpm -qa); do echo $f; rpm --setugids $f; done
2) for f in $(rpm -qa); do echo $f; rpm --setperms $f; done
3) yum reinstall openldap
4) signal-event post-upgrade; signal-event reboot
In advance I had to modifie the etc/resove.conf with the line: nameserver 8.8.8.8
because Names weren't resolved.
Now the modification is removed.
thanks a lot
Franz
