I got LDAP up'n'running, and for sure exim spits out a lot of queries
during its work! If you configured your LDAP server correctly and do
definitly provide a high speed connection between the two, you shouldn't
experience any difficulties. My LDAP is used for resolving aliases,
mantaining the addressbooks and authenticating users (exim, LAN). I sold
solutions like these to customers and they are highly pleased with it.

Keep the LDAP box free from the public to avoid load due to DoS or
similar games, keep down the amount of logging, and always remember:
You're running a dictionary server, not xeyes... so do provide enough
capabilities such as hard disk space, and CPU power - don't try the old
386 you might now be using as a door stopper ;).
