RE: OpenLDAP + Microsoft Outlook

Thanks for all of the insightful responses.

Many of the email clients mentioned either exclusively ran on LINUX or were
text based.  We are migrating most of our servers (WEB, EMAIL, FILE) over to
LINUX, but for the most part, we like the windows environment on our
desktops.  Users feel more comfortable with the OS.  

I've seen Evolution and it was nice!  Too bad it only runs on LINUX.
Anyway, we may just have to stick with MS Outlook 'till someone can come up
with something decent + GUI + open source on windows.

Simon, great information for perforamnce improvement.

Do you think this would speed up searches on a single OpenLDAP directory
with 50,000 + users? 

How could one get "display all" to improve to let's say 15 seconds?

Can "display all" be achieved in Microsoft's LDAP services without clicking
on find and then doing a search?

Also, to answer a question that started this string, I don't know anything
that deals with Microsoft that's "open source" in this area. Do you?

Thanks very much,
