Hello Noel,
unfortunately, EAP-TLS require certificates on both sides, which I
strongly need to avoid. Am I wrong?

Hello Volodymyr,
EAP-TLS seems to be widely supported as well. If the responder authenticates
itself first, the succeeding EAP exchange is encrypted and authenticated.
Kind regards
Noel

For example, it seems that MacOS (10.12 Sierra) native client supports only
EAP-MSCHAPv2 and rejects any other methods, e.g.
when I configure swanctl.conf in the following way:
connections {
ikev2-userpass {
[ ... ]
remote-1 {
auth = eap-peap
# auth = eap-ttls
}
}
}
I get the following messages in logs:
Mar 2 14:23:32 vpn strongswan: 16[ENC] <ikev2-userpass|4> generating IKE_AUTH
response 1 [ IDr CERT CERT AUTH EAP/REQ/PEAP ]
[ ... ]
Mar 2 14:23:32 vpn strongswan: 11[ENC] <ikev2-userpass|4> parsed IKE_AUTH
request 2 [ EAP/RES/NAK ]
Mar 2 14:23:32 vpn strongswan: 11[IKE] <ikev2-userpass|4> received EAP_NAK,
sending EAP_FAILURE
and same for EAP-TTLS: "generating IKE_AUTH response 1 [ IDr CERT CERT AUTH
EAP/REQ/TTLS ]"receive EAP/RES/NAK
So the question is there an alternative to EAP-MSCHAPv2 which can be used on
mostly deployed clients?

Hi colleagues,
which, from your experience, is the lowest common denominator for EAP methods
availability on various clients (hardware appliances [Cisco, Juniper, Mikrotik,
etc], software clients [Windows, MacOS, iOS]), if we don't talk about
EAP-MSCHAPv2 ?
Since mschap use NTLM hash which isn't secure enough, it's not bad to store
credentials in backend in a non-reversable format like SHA2. Looking at the
following table -
http://deployingradius.com/documents/protocols/compatibility.html - I see two
possible ways to achieve this target: EAP-GTC or PAP, tunneled inside other EAP
method (TTLS, PEAP, other which require only server certificate).
So the question is - which pair of inner/outer EAP methods you will recommend
to choose in order to get support for most client types and to have ability to
store credentials in backend in non-reversable hash form?
Thank you.
