AW: problem with shared folders and acls - only able to share INBOX

[Christian Eisert]

Hi, 

i found the solution for my problem (RTFM)

doveadm acl debug  =>  Folder \.Subfolder cannot be accessed => dots in
maildir format

I added a 'Layout=fs' to the namespace definition.

Thanks and cheers
Christian

Betreff: problem with shared folders and acls - only able to share INBOX

Hi everybody, 

I have a problem that I cannot share subfolders of the mailboxes INBOX ,
e.g.  /Sent / Trash etc. but also no self created folders. 
The ACLs seem to be set right. 
I have the suspicion that the dictionary (
/var/lib/dovecot/db/shared-mailboxes.db ) is not updated - there are no
entries for the sub folders

I just cannot find the problem within my configuration. Many thanks for
having a look at it.

Cheers from Hamburg, Germany,
Christian
