[Dovecot] Segfault in ACL Plugin + user shared folders
Hi Timo, I have another problem, this time with user shared folders: User markus shared the folder ForTest to test: SETACL INBOX/ForTest test akxeilrwts dovecot-acl and shared-mailboxes.db have been successfully updated. As user test the folder (and #User namespace) is not visible. When I configure the shared namespace with list = yes, the namespace and folder became visible and accessible, but lines like this are logged: Apr 7 22:08:58 asterix dovecot: IMAP(test): acl vfile: reading file /var/spool/dovecot/users/test/Maildir/.Shared/dovecot-acl Apr 7 22:09:03 asterix dovecot: IMAP(test): Invalid namespace prefix %u/ vs % Apr 7 22:09:03 asterix dovecot: IMAP(test): auth input: uid=2000 Apr 7 22:09:03 asterix dovecot: IMAP(test): auth input: gid=2000 Apr 7 22:09:03 asterix dovecot: IMAP(test): auth input: home=/var/spool/dovecot/users/markus Apr 7 22:09:03 asterix dovecot: IMAP(test): maildir: data=/var/spool/dovecot/users/markus/Maildir:INDEX=~/Maildir/index/shared/markus Apr 7 22:09:03 asterix dovecot: IMAP(test): maildir++: root=/var/spool/dovecot/users/markus/Maildir, index=/var/spool/dovecot/users/markus/Maildir, index=/var/spool/dovecot/users/test/Maildir/index/shared/markus, control=, inbox=/var/spool/dovecot/users/markus/Maildir Apr 7 22:09:03 asterix dovecot: IMAP(test): acl: initializing backend with data: vfile Apr 7 22:09:03 asterix dovecot: IMAP(test): acl: acl username = test Apr 7 22:09:03 asterix dovecot: IMAP(test): acl: owner = 0 Apr 7 22:09:03 asterix dovecot: IMAP(test): acl vfile: Global ACL directory: (null) Apr 7 22:09:03 asterix dovecot: IMAP(test): acl vfile: reading file /var/spool/dovecot/users/markus/Maildir/.ForTest/dovecot-acl Apr 7 22:09:08 asterix dovecot: IMAP(test): Invalid namespace prefix %u/ vs markus When I try to access the folder directly with list = children set, then dovecot segfaults.
