Bad Blogger....BAD!
I've not been updating as oft as I should, but wanted anyone / everyone to check out my most recent post at the Microsoft official Enterprise Platform Support DS blog - https://blogs.technet.com/askds/archive/2009/05/21/temporary-user-profiles-and-the-citrix-ica-client.aspx
It's a good read about temporary profile issues that can arise as the result of single sign-on with the Citrix 10.2x client installed.
This is a great blog to follow, as lots of people from the Directory Services specialty post information you might find helpful.
Also, my friend Russell Despain (aka Spaniard, aka R2) has started a blog specific to LDAP, and it's sure to be a good read!
