Hi,
I have the following configuration in my dovecot.conf for Dovecot 2.2.21:
passdb { driver = ldap args = /etc/dovecot/dovecot-ldap.conf.ext default_fields = allow_nets=local,127.0.0.1,10.255.1.0/24 }
This triggers "auth: Panic" on POP3/IMAP logins as the below:
Dec 22 14:57:39 localhost dovecot: auth: ldap(u0000,::1,<oiF8SHYngqsAAAAAAAAAAAAAAAAAAAAB>): allow_nets: Invalid network 'local' Dec 22 14:57:39 localhost dovecot: auth: Panic: file net.c: line 1137 (net_is_in_network): assertion failed: (IPADDR_IS_V6(ip) == IPADDR_IS_V6(net_ip))
doveadm auth test <username> <password>is no problem as expected.What's wrong?
allow_nets can only contain IP/network ranges. You can't use any names like "local". Anyway, it still shouldn't crash. This fixes it:
