Hi Team,
I am trying to setup mailbox sharing. But although user test2 shares
INBOX with test1, it is not visible for user1.
doveadm acl get -u test2 INBOX
ID Global Rights
user=test1 admin create delete expunge insert lookup post read
write write-deleted write-seen
cat /srv/mail/dovecot/lib/shared-mailboxes.db
shared/shared-boxes/user/test1/test2 at example.com
1

Is there anything obviously wrong in the config?
I suspect a mismatch between %u and %n somewhere but don't know how to
figure out the culprit.
How can I get more relevant debug log output about namespaces / mailbox
sharing?
Or can I run commands to check validity?
