Ldap search is slow , busy mail server

[Catalin Petrescu]

Hello   I have the following setup: openldap 2.2.36 qmail-1.03 + qmail-ldap-1.03-20050401a , courier pop3 + imap (with authlib latest version). The ldif looks like this : --ou=administrators                                       --ou=Groups                                                 --ou=Domain1.com                                                      [EMAIL PROTECTED] (this is a qmail-group for mailing list)                                                 --ou=Domain1.com                                                     [EMAIL PROTECTED] (same for domain2.com)                                     --ou=Users                                                 --ou=Domain1.com                                                      --ou=a                                                             [EMAIL PROTECTED] Etc.   The messages in queue takes too long to be delivered to users Maildir , I’ve turn on debugging for ldap and qmail does one search for mail address and the stop (unbind) for 2 sec and the starts all over again for the next mail.      I know that persistent connection is not an option with openldap , but for what I have read this setup (openldap +qmail-ldap) is one of the fastest and I this that I’m doing something wrong . Please give me an advice .     Catalin Petrescu
