Hi, I've recently migrated a server from a Qmail/VPOPMail setup to a Postfix/system accounts setup. Everything worked pretty much out of the box after just changing the passdb and userdb to pam and passwd. However, I cannot get my shared folders to work. In the logs I will always see something like Jul 21 07:24:10 mybox dovecot: IMAP(foobar): Namespace 'shared/': Could not lookup home for user bla Jul 21 07:24:11 mybox dovecot: IMAP(foobar): userdb lookup: connect(/var/run/dovecot/auth-master) failed: No such file or directory Now, I don't understand why I need auth-master to find the home directory of user "bla" (who owns the shared folder). However, even if I configure auth-master, only the error messages will go away but I still can't see the shared folders. The configuration (as shown below) worked fine with vpopmail and is just taken from http://wiki.dovecot.org/SharedMailboxes/Shared . What do I have to change to make this work with passwd instead? Do I really need auth-master? If yes, how do I need to set it up to do the job properly?
