The NM plugin currently does not provide an option to configure the
expected AAA server identity. So the IKE identity is reused and
enforced. This will fail if the AAA server uses a different identity

While the authentication method can't be configured explicitly in the NM
plugin, you can prevent the ẹap-peap plugin from getting loaded so plain
EAP-MSCHAPv2 will be used. To do so configure
charon-nm.plugins.eap-peap.load = no in strongswan.conf (note that this
requires at least 5.5.0 to work, in older releases the complete list of
plugins has to be provided in charon-nm.load, see  for details).
