Hello, I'm just upgrade Openldap v 2.0.27 (from RH 9 default pkg) to ver 2.1.21. Now it seems that client (evolution 1.2.2) was not able to bind, the error is "requested protocol version not allowed". After adding "allow bind_v2" to slapd.conf, those client works well. What is the drawback of "allow bind_v2"? should I user bind v3 only? Tks. --beast
