Daniel,
> f) I write a complete new frontend for managing everything.
I also use samba with the idealx scripts and was tired of using the M$ user manager, so I start writing my own user manager frontend in php that can create/modify/delete users and groups.
It was also implemented to manage postfix/cyrus mail accounts, but since we are gone use Zimbra now, I'm gone change it, so that it can manage zimbra accounts.
I think it will be ready in about one month, depending how long the user migration from Lotus notes to zimbra will take. (It will not be as fancy like the zimbra UI, but it will do the job).
I'll post the url when it's ready.
cheers,
Stefan
