Hi All!

After a lot of time waste to try to understand why I'm here to ask
Why! :-)

So I'v an Openldap server slapd 2.2.13 popolated with about 800 hundred
entries on a P4 2.6 with 512Mb.

I'v noted that on search of substring >3 the result are fast, about
1-3', but when I try to search anything under 3 char the server respond
after 450-500' with different search.

This is by design. I suggest upgrading to OpenLDAP 2.3.18, the latest release. In OpenLDAP 2.3, you can tune the number of characters at which substring searches respond to with the:

index_substr_if_minlen
index_substr_if_maxlen
index_substr_any_len
index_substr_any_step

parameters in slapd.conf(5)

Note that if you change these settings, you will have to regenerate any existing index data (run slapindex) in your database.
