[Swan-dev] nssdb is pointing to /etc/ipsec.d but it needs to point to the /usr/local/platform/.security/ipsec path provided in /etc/ipsec.conf

Can you try CentOS 7.5 with libreswan 3.23 ? We fixed some things to
ensure the nssdb could be in /var/lib/ipsec/nss for Debian, so it
should really work for you as well.

That is a pluto commandline argument, not an ipsec.conf option? The
option for that would be logfile=directory

esp= and phase2alg= are aliases. Both can be used.

There is no auth= option. There is authby= or leftauth= / rightauth=

The /etc/ipsec.d directory contains a bunch of config files AND the nss
binary db files. Now using ipsecdir and nssdir, you can split this and
keep the configs in /etc/ipsec.d/ and keep the nss *db binary files in
another dedicated nss directory (eg /var/lib/ipsec/nss on Debian)
