[Dovecot] imap dump-capability fails Dovecot 1.1.6
Hi Timo,
Dovecot fails to start after upgrading from 1.1.4 to 1.1.6:
Fatal: userdb didn't return a home directory, but mail location used it (%h): %h/mail:CONTROL=%h/control:INDEX=%h/index Error: imap dump-capability process returned 89 Fatal: Invalid configuration in /etc/dovecot/dovecot.conf
Adding a fake home directory to args in master-settings.c:get_imap_capability solved the problem for me, but there may be a more correct fix.
Regards, Thorsten

Yes, that's the correct fix: http://hg.dovecot.org/dovecot-1.1/rev/2fbd36039526
One workaround is to use ~ instead of %h. It'll log errors, but it still works.
Wonder how many people will have this problem.. Perhaps I'll have to release 1.1.7 just because of it.

With the corresponding fix in dovecot-1.2 dovecot doesn't start anymore for me: setgid(65534) failed with euid=1001, gid=1001, egid=1001: Operation not permitted Error: imap dump-capability process returned 89 It turns out that rev 2fbd36039526 changed the indices in the args array that some other code get_imap_capability relied on so that the uid and gid are not overwritten properly when dovecot is not started as root.

Oh. Right. It didn't give that error with me, so I assumed it worked. Well, I fixed it just by moving home to last: http://hg.dovecot.org/dovecot-1.1/rev/cbde69815b8a

Hmm. It does that?
