Unfortunaly I cant compare those numbers to anything netscape 
puts out.

Yes I agree this is all hardware dependant since openldap runs on 
pretty much any Unix but Netscape DS only runs on solaris. 

Can anyone related their experiences running openldap with greater 
then 20k or 30k entries? We are planning on using it for single sign 
on essentially. Basically I am looking for real world testimonials. 
Has it performed well for you? Is it stable? What OS do you run it 
on? 

Thanks for any help you can offer..
