Define and macro by setting as environment variable:
EJABBERD_MACRO_ + macro name
For example, if you configure in ejabberd.yml:
define_macro:
LOGLEVEL: 4
loglevel: LOGLEVEL
You can define (and overwrite) that macro definition when starting ejabberd:
EJABBERD_MACRO_LOGLEVEL=5 make relive
XEP-0388 says: "SASL2 MUST only be used by Clients or offered by Servers
after TLS negotiation". Therefore, we reject SASL2 negotiations over
unencrypted transports by default. However, TLS might be terminated
outside of ejabberd. Add the 'allow_unencrypted_sasl2' option to
support this use case.
This allows connections to server that have both xmpps-server and xmpp-server
srv entries, for which xmpps version doesn't work correctly. Before this
change we would stop on non-working xmpps server, now we will also attempt
to connect further servers on list.
