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,

You can't use any names like "local". Anyway, it still shouldn't crash. This fixes it: https://github.com/dovecot/core/commit/f53a1b98d6792a3aa28474fca0901b1de035f8ba

You can't use any names like "local". Anyway, it still shouldn't crash. This fixes it:Dovecot 2.2.15 has the following change: + passdb allow_nets=local matches lookups that don't contain an IP address (internally done by Dovecot services) I use the "allow_nets=local" to allow administrtors to run `doveadm auth test username`. If allow_nets has no "local", it is failed (rejected?). Is this a bug? # doveadm auth test foobar Password: correct-password passdb: foobar auth failed extra fields: user=foobar> https://github.com/dovecot/core/commit/f53a1b98d6792a3aa28474fca0901b1de035f8baThank you! -- -- Name: SATOH Fumiyasu @ OSS Technology Corp.
