osx hangs on logoff white screen while shares are mounted

Hey everyone,

While testing logging on and logging off I stubled onto the following issue:

While logging on with a Mobile account using Active Directory credentials and then disconnecting wifi or pulling out the ethernet adapter (simulation network loss) and finally logging off, the mac seems to hang on a white screen and no longer reaching the login window.

When I dismount the shares before logging off this problem does occur.

This only happens while network shares are mounted and the users are logged in with a active directory mobile account.

I've tried unmounting the shares with a script in a policy (policy is available offline) that runs on the logoff trigger but it looks like the mac hangs before it has a chance to run the loggoff policies.

I've experienced this on OSX 10.8.5 and 10.9.5.

Has anyone else run into this behavior?

After looking though the logs a bit more I noticed the following lines:
