#1 Connection problem

[Aurélien Coq]

I've downloaded LDAP Navigator and i'm trying to admin
openldap 2.0 with it.
- I've installed apache and php on my computer (redhat 8.0)

I've configured config.php in order to use
LDAPNavigator and the parameters should be OK (they
work fine when connecting using LDAP
browser/adminiatrator 2.8.1)
However, on the index page, when trying to connect
(click on start), nothing happens and the page is just
reloaded without any error message. If i modify the
connection settings on index.php and then hit start, it
goes the same, even it the parameters are completely wrong.

Why don't i get error messages? What should I check?
