-File-based rights.
-
-The owners are implied to have all rights on their collections.
-
-Rights are read from a file whose name is specified in the config (section
-"right", key "file").
-
-Example:
-
-# This means user1 may read, user2 may write, user3 has full access.
-[user0/calendar]
-user1: r
-user2: w
-user3: rw
-
-# user0 can read user1/cal.
-[user1/cal]
-user0: r
-
-# If a collection a/b is shared and other users than the owner are supposed to
-# find the collection in a propfind request, an additional line for a has to
-# be in the defintions.
-[user0]
-user1: r
