Hi guys, I am upgrading our Cyrus installation from 2.2.12 to 2.3.14 and just started looking at ACLs. When I attempt to deliver to a mailbox with "group:" ACLs, LMTP crashes and will not deliver the message. Here's the ACLs for the mailbox: timaphost.bath.ac.uk> lam user.exim exim lrswipkxtecda ma9djm lrs group:exim lrs This is a grab of me doing an LMTP session to the frontend: 220 timaphost.bath.ac.uk Cyrus LMTP Murder v2.3.14 server ready LHLO timaphost.bath.ac.uk 250-timaphost.bath.ac.uk 250-8BITMIME 250-ENHANCEDSTATUSCODES 250-PIPELINING 250-SIZE 250-STARTTLS 250-AUTH EXTERNAL 250 IGNOREQUOTA MAIL FROM:<> 250 2.1.0 ok RCPT TO:<exim@xxxxxxxxxxxxxxxxx> Connection to localhost closed by foreign host. Relevant imapd.log lines: May 29 15:57:53 sauber-z1.bath.ac.uk master[16505]: [ID 970914 mail.error] process 16674 exited, signaled to death by 11 May 29 15:57:53 sauber-z1.bath.ac.uk master[16505]: [ID 621917 mail.debug] service lmtp pid 16674 in BUSY state: terminated abnormally If I take the group:exim ACL off the mailbox, it delivers fine. The Unix group exists on the MUPDATE master and the backend. Relevant bits of imapd.conf: seenstate_db: skiplist duplicate_db: skiplist subscription_db: skiplist quota_db: skiplist sasl_pwcheck_method: saslauthd sasl_mech_list: plain gssapi allowanonymouslogin: no allowplaintext: yes auth_mech: unix We are using Cyrus-SASL/GSSAPI for authentication. We built imapd-2.2.12 with --with-auth=unix but configure-2.3.14 does not have this option so we've set the auth_mech option in imapd.conf as above. Do any other values need to be set in configure or imapd.conf for this to work? Can anyone suggest how to make this work and/or where to look for more information about why it's failing so horribly.
