Hi all, Sorry this is embarrassingly simple, but I'm struggling a bit with it. Profuse apologies if I missed something obvious. We use MAC authentication with some stuff, and update the control Cleartext-Password to match the user-name field, as mac auth on the NASes here always use that as the password. Authorisation does all our useful accept/reject stuff, not authentication. Having said that I'd prefer not to "hack" it to bypass auth. My test NAS is an HP/Aruba 2530 with v15.17.0009 firmware Before the chap auth runs: Update control { &Cleartext-Password = &User-Name } Works on v3:
From the access request : Wed Jul 22 08:33:57 2020 : Debug: (0) User-Name = "08000f510d1e" Wed Jul 22 08:33:57 2020 : Debug: (0) CHAP-Password = 0x9fdc274c2e3ca36a66a0581a10d44a7dd2 Wed Jul 22 08:33:57 2020 : Debug: (0) Message-Authenticator = 0x978dc5f6ccbcd916950b3d76190039dc .. .. and then the chap auth debug: ..

But on v4, it doesn't like it, and I can't figure out why, says the password is incorrect. I've checked and double checked the client.conf secret is correct.

Can anyone spot the issue?
