Description ayaka 2014-08-05 09:58:16 UTC 
Description of problem:
I configure postfix with dovecot using lmtp.
I configure two passdb, one is auth-system the other is auth-sql
I works fine for pop3 but I can't work with lmtp. It would cause a segfault.
If I remove auth-system, it works fine.

Version-Release number of selected component (if applicable):
postfix 2.10.1 6.el7
dovecot 2.2.10 4.el7_0.1
dovecot mysql 2.2.10 4.el7_0.1

The Red Hat Enterprise Linux 7 life cycle has entered Maintenance Support Phase, which means that only qualified Critical and Important Security errata advisories (RHSAs) and some Urgent Priority Bug Fix errata advisories (RHBAs) will be released as they become available.  Unfortunately, this issue was not selected to be included in Red Hat Enterprise Linux 7. We will now close this issue. We recommend moving the request to Red Hat Enterprise Linux 8 if applicable.
