Hi, I recently upgraded to openSuse 12.1 which comes with dovecot 2.0.14. Because of mail-client-problems I am running one dovecot which requires authentication via a client-certificate and another one which can be used without a certificate. (Configurations can be found below.) Since the upgrade our shared mailbox is no longer visible. I tried to repair this by setting the ACLs once again (using imap-acl in Thunderbird) but every time I try to set a new ACL the tool says "noaclright" and dovecot logs the following messages:

Dec 7 14:31:14 mailbox dovecot: imap(<sharing-user>): Error: fstat(/home/<sharing-user>/Maildir/.<shared-folder>/dovecot-acl.lock) failed: No such file or directory Dec 7 14:31:14 mailbox dovecot: imap(<sharing-user>): Error: file_dotlock_open(/home/<sharing-user>/Maildir/.<shared-folder>/dovecot-acl) failed: No such file or directory

Needless to say the file exists and its contents looks like it should. (Every line is an ACL like "user=testuser ilrws") I took a look at the changelog from 2.0.14 onwards and since it says nothing about my problem I am not looking forward to compiling dovecot myself and installing it.

Any ideas why this is happening? Is this a known problem?

Any help is appreciated, Knud
