Choices, choices. choices??!?!

OK people,

It has to be asked: –

Which directory services? And why?

eDirectory
Active Directory
iPlanet
a.n.other

I’m not talking small time networking. We have 5,000 staff in Europe with approx. 7,500 in the US with a further 1,000or so in Oz. We are using an NT4 domain with NetWare servers for file store.

Anyone got a view on which directory services???!??!??!
