One irritation that I have seen that I cannot find a way round is that when you run a program requiring sudo e.g. Synaptic it may ask you for the password of a LOCAL user, not the domain user. I think that an extra module line is probably required in pam but not have figured out how as yet.

I believe adding your new group to the following file will then present you with a list of users who can authenticate:
It will present an 'Authenticate' box with a list of users - I have not yet found how to just accept the password for the current logged in user (as per normal case for standalone user). Most likely it requires a modification to lightdm similar to above.
