True. But Exim is the client and only has to accept the LDAP server's
certificate. Which he apparently does through /etc/ldap.conf.

Yippee. One who backs me up. Actually, my whole post was about Exim
4.1.12 and Openldap 2.1.10, and how my troubles went away. However,
don't try Openldap 2.1.11; apparently it's broken.

Yes. But one would have to appreciate my particular conditions to
understand *why* I should have 100% disk (not bus) utilization. I'm too
embarassed to say why, but I can't get away from it. Just say that I'm
now 110% happy.

Definitely.

I'll take the "Happy N.Y. and Merry Xmas" on account, thanks. Same to
you in 2003/2004 :)

Best,

Tony
