update dovecot-acl in all subfolders in a public folder

14 Oct 2016


      Hello everyone,
right now I have problem and can't find a proper solution.
But first: dovecot-version: 2.2.13
Now to my problem:
A client of mine uses a public folder called "groups". In this Folder
are several subfolders like "Archive", "projects", "sales" und so on.
Unfortunately this client (and his employees) created thousands of
subfolders within these folders. The folder "groups" is stored in
/data/vmail/domain.com/.
So, if i type "tree -a -L 1 /data/vmail/domain.com/groups" I get the
following outpout:
/data/vmail/domain.com/groups/
??? .Archive
??? .Archive.subfolder1
??? .Archive.subfolder2
??? .Archive.subfolder2.subfolder3
??? .Archive.subfolder2.subfolder4
(....)
??? .projects
??? .projects.subfolder1
??? .projects.subfolder2
??? .projects.subfolder2.subfolder3
??? .projects.subfolder2.subfolder4
(...)
In this groups-folder are at the moment more than 3400 folders!
Now to the permissions:
When the folders "Archive", "projects" and so on had been created every
folder got a dovecot-acl for the permission for each user, e.g.:
user=user1 kxeilprwts
user=user2 kxeilprwts
This worked finde, as the dovecot-acl got copied from the parent folder
when the employees created new subfolders.
Now to my problem I'm facing right now:
This client got 2 new employees. So how can I edit all these dovecot-acl
files in all subfolders where these 2 new employess schould get access to?
Thank you in advance!
Yours sincerely,
Lukas Henrich
