Looks like this is being caused by bare `maps::at`s on the config data structure. The config data structure is populated from from the plist table which in turn contains information from all plists in

/Library/Preferences/OpenDirectory/Configurations/Active Directory/

. I can't repro on my system because I must not be hitting that particular case 😞. @kyle do you have any more steps to repro this? The fix to stop the crash is we need to fix the bare `map::at`s but the fact that this is crashing at all suggests a case was missed which also needs to be addressed.
