allow_nets=local in passdb gets "auth: Panic"

[SATOH Fumiyasu]

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?

Regards,
