These are all because of the way that OS X handles security sessions.   
If you log in via ssh, start some child processes, then log out, the  
user's session is torn down, disabling certain abilities (like  
DirectoryService authentication) for child processes that linger about.

The best way to use buildbot under OS X is to either a) launch it from  
a terminal window on the slave, or b) create a launchd plist to run  
the slave as.  Over ssh, you can sometimes start the buildbot slave  
with "nohup buildbot start <pathToMaster>" (man nohup for more) but  
even that's not guaranteed to work.
