Re: [Samba] Execute a user script whenever a user is added in the domain

My DC handle the authentification and some other Samba server provide
shares (they're pure file servers with winbind). Users get their personal
directory as a share with appropriate permissions.

Up until now I used a Samba 3 server to both handle the authentification
and act as a file server. I had a script to create a Samba user, create the
personal directories and set some ZFS quota on it.

Now with AD I want to allow people to easily be able to create users with
the ADUC tool. The DC now is on a separate machine then than file server.
But I still need a way(script) to automatically create the directories.

I already tested using the "add user script" on the file servers, but since
they use winbind, I guess they "find" the user and the script isn't
executed. I think I found a solution though by using 'root preexec', like
suggested here: https://serverfault.com/a/576142/437431

But I would still be interested in also having a way to run a script on the
DC, to add the user to some mailing lists there.
