Re: slapd connection delays

[Jens Vagelpohl <jens@digicool.com>]

this might be a DNS issue. by default the server will try to do a reverse
lookup on the client connection coming in.

check your DNS setup and if you don't want to use DNS you could compile the
daemon yourself without the reverse lookup (see "./configure --help")
