Management of the reply Message (reason why the authentication failed) :

multiple authentication servers can be used, so multiple reply messages could theoretically be returned.

But only one message is returned (the most important one).

|
The return value of authenticate_user() define how important messages are :
|
|
1216
|
- Reply message of a successful auth is more important than reply message of
|
|
1217
|
a user failed auth(invalid credentials/authorization)
|
|
1218
|
|
|
1219
|
- Reply message of a user failed auth is more important than reply message of
|
|
1220
|
a server failed auth (unable to contact server)
|
|
1221
|
|
|
1222
|
- When multiple user failed auth are encountered, messages returned by remote servers
|
|
1223
|
(eg. reply in RADIUS Access-Reject) are more important than pfSense error messages.
|
|
1224
