Update HomeDirectory Field when User has a Specific Group added (and removed) to their account

IMO, it would be better to approach this by watching for add / remove members from your group.

Have one change workflow trigger on the add member and one trigger on the remove member.

You can specify the group name in the filtering section at the bottom of the workflow start conditions dialogue.

That makes sense. I have tried that option, but found when I use the "Change Object Properties" option in the workflow, it is trying to change the homedirectory on the group instead of the user. Is there another option or script I should be using to update the homedirectory value when the user is added or removed from the group above?

Yep - you will have to code obtaining the names of the members that were added or deleted from the group.  It's part of the "payload" of respective add/remove transaction.  I don't have that handy but someone else may chime in.
