check_ldap

hi,
the chek_ldap plugin doesn’t work on my configuration (nagios-2.0rc2, nagios-plugin-1.4.2, Ubuntu-5.10)
If I launch ./check_ldap -H -b dc=,dc= it returns “Could not bind to the ldap-server”.
But if I use any ldap-browser with the same parameters, I bind the server

I modified “default protocol” from 2 to 3 and all is ok now
