This dn is wrong: it should read

dn: cn=whois\+\++ipServiceProtocol=tcp,ou=Services,dc=int-evry,dc=fr

that is, the '+' before ipServiceProtocol must not be escaped.
Moreover, while you need to escape '+' in dn, you don't
in attribute 'cn' (I think, at least); as a result you can search
it normally.
So your entry should be:

dn: cn=whois\+\++ipServiceProtocol=tcp,ou=Services,dc=int-evry,dc=fr
objectClass: ipService
objectClass: top
ipServicePort: 63
ipServiceProtocol: tcp
cn: whois++
description: IP service 63 (whois++)

Please correct me if I'm wrong.
