I am creating a public folder as per the documentation.  I added only one of my users (m@mydomain.com) to the ACL, yet now every users (appears to) have admin rights!

Am I misreading the output of the get command below?  Why when I add one "user", does the ACL have "usernames" for everyone on my server, with "ID" matching my username?

[root@mail public]# doveadm acl set -A "Public/TEST" "user=m@mydomain.com" admin
[root@mail public]# doveadm acl get -A "Public/TEST"
Username          ID                 Global Rights
d@mydomain.com     user=m@mydomain.com        admin
h@mydomain.com     user=m@mydomain.com        admin
k@mydomain.com     user=m@mydomain.com        admin
m@mydomain.com     user=m@mydomain.com        admin

Perhaps the documentation needs an update if the above is correct.  I just can't understand it.
