Hi Badlop,

Thank you for this patch, now further it appears that the API methods check_password/3 and check_password/5 have been changed to check_password/4 and check_password/6 respectively in auth modules, so encountering below error:

gen_fsm <0.580.0> in state wait_for_sasl_response terminated with reason: call to undefined function ejabberd_auth_http:check_password(<<"user">>, <<"password">>, <<"server">>, <<>>, <<"8021545d530d14a388d17f094d195a7b">>, #Fun)

If you have a patch for this as well it would be helpful.
Else please help me understand the new argument "AuthzId".

UPDATE: The changes made in the ejabberd_auth_http file to implement check_password methods with 4 and 6 arguments are not reflected even after successful compilation of this module. Why could this be?

Thanks.

Right, it expects a new argument called AuthzId, so let's accept it even if it isn't used:

Well, remember to compile and copy the beam file to the "proper place".

Thanks, works like a charm!

Now I have hit a further blocker and have started a new thread for that. The problem being, as it seems, BOSH is still using default authentication, whereas I have used SCRAM in other modules.

So does BOSH support SCRAM authentication, and if it does want changes do I need to make?

Thanks.
