Unable to connect to server, receiving Invalid username or password response #3

Closed sheuertz closed 6 years ago

Hi,

I'm trying to incorporate your module into ejabberd. It shows as installed, and the auth_mode is set to jwt. To test the connection, I'm using a simple JWT created on http://jwtbuilder.jamiekurtz.com/. I'm just using the HS256 default secret on that site when generating the JWT.

I am trying to connect using Pidgin. I set the username to match the sub claim, and the password to the token, but when it tries to connect, I get an Invalid username or password message.

15:22:14.378 [info] (tls|<0.734.0>) Failed c2s PLAIN authentication for jrocket@example.com from ...

I can see in the log that the token is getting to the server, but I can't tell if the jwt auth module is being used to authenticate. Is there any guidance you can give if I'm doing something wrong based on the above?

Hi,

Sorry it took so long to answer. I suppose you found a solution by now, but I will post this anyway to help future users.

The HS256 key attribute was expecting a base64 encoded key. This was not very well documented. I just changed this behaviour:

https://github.com/yokomizor/ejabberd-auth-jwt/commit/e80a3ae300a68c4f288685efc60a7864b20d0f32#diff-6d9d5cd5f19344fb1c266c579f878716R116

Before

jwtauth_key: "U0VDUkVU" # Base64 encoded key
jwtauth_strict_alg: "HS256"

Now:

auth_method: jwt
modules:
  ejabberd_auth_jwt:
    key: "SECRET" 
    strict_alg: "HS256"
