Slow login (Active Directory User + Filevault2) - Mountain Lion Two of our users have been getting this weird issue where their login to the computer seem to take "ages".

The issue seems to go away if you turn off FileVault.

However we need to keep FileVault on, but as this only effects a small number of users it seems like this is some specific issue with just their computers.

Info about the computers:


MacBook Pro (Retina) - Early 2013 
Mac OS X 10.8.2 
FileVault 2


Connected to Active Directory (Network Account Server)

sudo defaults write /Library/Preferences/com.apple.loginwindow DSBindTimeout -int 8

Changes the bind timeout to 8 seconds. Our bind happens within 3-4 seconds over ethernet, so we figure double it and add an extra second should be enough for an absolutely unscientific unengineering-like guess.
