Unable to change 'sieve' annotation of shared mailbox on 3.6.1

[igogold]

I have issue on debian 12 version 3.6.1 of cyrus imapd. I unable to execute mboxcfg on any shared mailbox. But on user's mailbox I can change with mboxcfg a comment, for example.

I have sasl_pwcheck_method: saslauthd settings and run saslauthd -a kerberos5 to auth via AD domain. So my imap admins are: admins: cyrus kerbcyrusadm.

I have admin.sieve.script and compiled admin.sieve.bc in /var/spool/cyrus/sieve/global. When I login via cyradm and try to change sieve annotation of shared mailbox admin the imapd terminates.

mailbox:~# cyradm -u kerbcyrusadm -w MY_CYRUS_ADMIN_PASSWORD localhost

Yes, consistent

Full restart of cyrus-imapd service doesn't help also. What's wrong with my installation?

I've tried to change ACL for kerbcyrusadm user to all on the mailbox, doesn't matter.

I update from version 3.2.6 in debian 11 to 3.6.1 in debian 12 and add mailbox_legacy_dirs: yes into imapd.conf.

I applied PR #4613 and the error has gone. Now I can apply sieve script to any shared folder again.

This bug is still present on cyrus 3.8.3 :

grep ^admins /etc/imapd.conf

admins: admin

sieveshell -u admin -a admin localhost

cyrus 3.8.3 doesn't recognize the administrator user and try to create user.admin.#sieve mailbox.

I did managed to create "global scripts" in /var/spool/sieve/global, and compile them and attach them to shared mailboxes. But they are not used by lmtp to deliver mails.

I (or cyrus) should certainly create shared-box.#sieve, but I don't know how to do that.

Sincerly,
