Public folders method 2

 

• Login to GCSX

  Check if the user already has permissions to the folder:   This example looking at folder "folder1" for user derek.cooper  

doveadm acl debug -u derek.cooper@the.domain.com Folders.Public.folder1

 

doveadm(derek.cooper@the.domain.com): Info: Per-user private flags in mailbox: \Seen
doveadm(derek.cooper@the.domain.com): Info: User derek.cooper@the.domain.com has rights: post
doveadm(derek.cooper@the.domain.com): Error: User derek.cooper@the.domain.com is missing 'lookup' right
doveadm(derek.cooper@the.domain.com): Info: Mailbox Folders.Public.folder1 is NOT visible in LIST

  The last line shows the folder cannot be LISTED by the user.  

• add the user to the public folder access control list

  Again adding the user derek.cooper to the "folder1" folder  

vi /mail/public/.Public.folder1/dovecot-acl

  And add the users full login account:  

owner lrwstipekxa
anyone p
user=michael.powell@the.domain.com lrwste
user=chris.martin@the.domain.com lrwste
user=james.stocks@the.domain.com lrwste
user=michael.powell@the.domain.com lrwste
user=paul.clewer@the.domain.com lrwste
user=paul.davies@the.domain.com lrwste
user=derek.cooper@the.domain.com lrwste

 

• Remove the old list index file to force the new permissions to be active

 

rm -f /mail/public/dovecot-acl-list

 

• Check the users permissions for the folder again.

 

doveadm acl debug -u derek.cooper@the.domain.com Folders.Public.folder1

 

doveadm(derek.cooper@the.domain.com): Info: Per-user private flags in mailbox: \Seen
doveadm(derek.cooper@the.domain.com): Info: User derek.cooper@the.domain.com has rights: lookup read write write-seen write-deleted expunge
doveadm(derek.cooper@the.domain.com): Info: Mailbox found from dovecot-acl-list
doveadm(derek.cooper@the.domain.com): Info: Mailbox is in public namespace
doveadm(derek.cooper@the.domain.com): Info: Mailbox Folders.Public.folder1 is visible in LIST

  This time not the last line says the folder is visible.  

• Now add the folder to the users subscriptions file:

 

vi /mail/the.domain.com/derek.cooper/Maildir/subscriptions

  Then add the Folders. and Folders.Public.folder1 lines (note the case)  

Sent
Trash
Drafts
Folders.
Folders.Public.folder1
Folders.Public.folder2
test2
Sent Messages
Queue

 

• Get the user to login out, wait a few mins, then log back in. They should now see the folder in the mailbox list.
