This was a change in perl-ldap 0.45 to "Make IPv6 usage more sane",
 https://rt.cpan.org/Public/Bug/Display.html?id=77458

With resolving this bug, perl-ldap switched to the "standard" of using either
IP version when no option was given, and changed the meaning of
the 'net6' option from "try IPv6" to "only use IPv6".

This is reflected in the documentation.

I see two options for amavis to fix it:
* raise the required perl-ldap version to 0.46 and remvoe "inet6 => 1"
  from the constructor fo theNet::LDAP object
* make the addition of inet6 => 1 dependent on perl-ldap's version
