Hi. I have a setup with 1 frontend, 1 murder, 2 backends. I am playing with cross-backend mailbox sharing, one of the features we value most. Problem. While I can access shared mailboxes that reside on the same backend just fine, with Thunderbird (1.5/linux) I can see shared folders on other backends, but when I subscribe nothing is subscribed. Thunderbird always connects to the frontend machine. All cyrus servers have the same Invoca RPMs (v2.3.14-Invoca-RPM-2.3.14-2). Authentication via PAM LDAP, if that matters. I use virtdomains but all accounts are under the same @domain . ACL are "anyone lrs". Summarizing: I can access shared mailboxes on the same backend, but on different backends they cannot be subscribed, Something I should look for?
