Hmmm, well in my setup dovecot-lda is called from Exim with "user="
set to a MySQL query.
Are you sure you even need Dovecot to do a userdb lookup then? If
Exim can set up also the other needed things (home dir?) it
shouldn't be necessary.
Yeah, I think I could do that. I followed the setup guide for Exim
from the Dovecot wiki and this is the first config I arrived at, which
works well apart from this little detail.
Hmm. So if dovecot-lda is running as vmail group and
/var/run/dovecot/auth-userdb has group=vmail and 0660 permissions,
this error shouldn' t happen. Check two things:
1) ls -ln /var/run/dovecot/auth-userdb actually shows group as 25110
and mode being 0660
srw-rw---- 1 root mailnull 0 Aug 23 19:13 /var/run/dovecot/auth-userdb
2) If you've any SELinux or app-armor stuff enabled, try disabling them
Im running FreeBSD so no SELinux here.
In my test, actually what I have is a vmail user with primary group
vmail and secondary group mailnull. Which as mentioned results in this
error:
Aug 23 19:19:13 lda: Error: userdb lookup:
connect(/var/run/dovecot/auth-userdb) failed: Permission denied
(euid=25110(vmail) egid=25110(vmail) missing +r perm:
/var/run/dovecot/auth-userdb, euid is not dir owner)
It did cross my mind it was a bug, but then I thought the
documentation just was wrong on the wiki...
