I've actually tried them out and it works great. Nice piece of work Greg .
After using it for a few weeks, I would like to make the following suggestions:
a) Add an option to expire the Samba password to force them change the password.
b) In the memberuid option under Posix Groups: Could you add an option to allow the users to select a single or multiple zimbra users to fill them up quickly?
c) Add an additional button to display all users that belongs to this particular Posix Group.
d) Add an additional button in the user profile screen that displays all the groups that he/she belongs to.
Can't wait for the next version of this zimlet
