LDAP - speed question

[cs-cam]

Hey all,

I'm writing a little app to make some of the AD management tasks single click jobs for my offsider and I'm also using it as an opportunity to learn some C#. I'm doing ok so far, I've decided to create a user class that contains the AD object properties with the intention of expanding it later. For now I only really need it to have the displayName and distinguishedName which works fine but I thought I might as well just populate a Hashtable with every property in case I use them later.

What I have so far: http://pastebin.ca/1487675

I'm working with groups of around 500 users, when I create 500 of these to loop through it works but takes AGES. Now if I remove the foreach() loop and just set the two names its almost instant. Pretty much I'm just asking am I doing something wrong or is it normal to take that long querying an LDAP server and I should cut down the amount of info I'm trying to pull out?

Cheers.

You've hit the nail on the head: the AD LDAP provider lazy loads information to improve performance, I think it best to follow the pattern
