[strongSwan] swanctl.conf EAP credential information

[bls s]

I’m switching over from using IPsec.conf to charon-systemd. Everything is working for the first user, but I have run into a strange issue (or a dumb user error!) with the ‘secrets’ section when trying to implement multiple eap passwords.

If my secrets section has only one eap id/password in it, the client authenticates correctly. But, if the secrets section has more than one eap id/password in it, the MSCHAPv2 authentication fails.

Here’s the failing configuration. If I remove the 2nd and 3rd entries, user1 works correctly. However, using the full secrets section below, user1 fails to authenticate.
