Normally, in the chain of directories, password repositories, authentication middleware, etc. you lose the information about the reason the authentication fails.

This results in a 0 or 1 condition of authentication success or authenticatio fail. There are some radius attributes you can use out-of-standards to report about reasons, but since is an out of standardization use, this will not be grabbed by clients (supplicants).

This scenario is typically a lot different from a simple WPA passphrase authentication.

What I assume as an oversemplification (that means complication) of the scenario is also the operating system behaviour of re-requesting for secrets when something goes wrong such as:

- Temporary Timeouts (backends, radius hierarchy, ...)

- Errors in wifi (low signal and subsequents retransmission and timeouts)

- Wrong/unsupported authentication mechanisms

- TLS version mismatch and implementation issues

- ...

All those reasons should not lead to re-asking the user for password (default behaviour on windows and other os).

Users forget and unknowingly mistype their passwords. This leads to a worse user experience perception (think about retyping password due to a home server temporary unreachability).

The profile re-installation is a safer and better solution for what I understand.

Why would this be specific to the operation of Windows and not eduroam?

 

Because when connecting to an access point with a simple SSID such as “WPA2 PSK”, Window asks you to re-enter the password security key.

 

Which would suggest that in WPA2-Enterprise / AES / PEAP mode it behaves differently?

 

This could not be due to the fact that the Freeradius server does not indicate to the Windows client that the password is invalid?

 

Good day

Unfortunately this is how Windows works now, if you run the installer again it will remove the profile and install everything again. You could also "forget" the eduroam network, but this would result in the same thing - the need to run the installer again.

Good morning,

 

After eduroam configuration of the Windows machine (10/11) via “eduroamCAT” or “geteduroam”, the connection works.

 

On the other hand, when our users change the password in our directory, they are refused the connection.

 

But the Windows client never offers to enter the new password, so there are two questions belows:

 

• Why this behavior?

• How to force Windows clients to ask for the new password?

 

Sincerely,
