Errors from error.log/crash.log

No errors

Bug description

With this basic config, running a compliance test via https://compliance.conversations.im returns:

Server doesn't support any of the requested SASL mechanisms: [SCRAM-SHA-1, DIGEST-MD5, GSSAPI, CRAM-MD5, PLAIN, ANONYMOUS].

with no errors in ejabberd log

Change auth_scram_hash: sha512 to sha1 ?

licaon-kter avatar Nov 20 '23 05:11 licaon-kter

sha1 is invalid, assuming sha

results in the same error

itzzengay avatar Nov 20 '23 12:11 itzzengay

So you've setup auth_scram_hash: sha and reload_config and still fails with the exact same error message?

Ok, can you unregister, then register again the test user?

licaon-kter avatar Nov 20 '23 12:11 licaon-kter

@prefiks: Can you look here?

Neustradamus avatar Nov 21 '23 14:11 Neustradamus

You will need to change password of users you created (stored password will be using sha512, and they aren't compatible with sha1 authentication), you can use ejabberdctl change_password username your.domain newpassword

prefiks avatar Nov 21 '23 14:11 prefiks

Recreating the user has the same effect :)

licaon-kter avatar Nov 21 '23 15:11 licaon-kter

I have had sha512 work before, and I would like to keep using it. This is a different problem.

For example: using plain authentication does not work, I still get the "Server doesn't support any of the requested SASL mechanisms" error

itzzengay avatar Nov 22 '23 15:11 itzzengay

Maybe we are lost in translation?

    auth_password_format: scram
    auth_scram_hash: sha512

...means there's no PLAIN, no SCRAM-SHA-1, no SCRAM-SHA-256 because you set it up like that

If your testing client cant use only PLAIN, if the caas powering the Compliance page can only use SHA-1, then, as expected, they can't login and will fail.

Now, what are you trying to do?

licaon-kter avatar Nov 22 '23 16:11 licaon-kter

sha512 does work with caas, I have tested ejabberd servers using sha512 and scram before and it works without the error it's giving me now.

I temporarily changed the auth_password_format to plain to see if that would change anything, and it did not.

itzzengay avatar Nov 22 '23 16:11 itzzengay

I temporarily changed the auth_password_format to plain to see if that would change anything, and it did not.

and restarted server and and un-registered the test account, then re-registered the test account?

licaon-kter avatar Nov 22 '23 16:11 licaon-kter

@itzzenxx can you run CaaS locally in debug mode and see the output?

licaon-kter avatar Nov 22 '23 16:11 licaon-kter

How do I run CaaS in debug mode?

itzzengay avatar Nov 22 '23 17:11 itzzengay

java -jar caas-app/target/caas-app.jar --verbose [jid] [password] I guess https://codeberg.org/iNPUTmice/caas

Can you attach the latest config again?

licaon-kter avatar Nov 22 '23 17:11 licaon-kter

the config for ejabberd is unchanged from my original post

itzzengay avatar Nov 22 '23 17:11 itzzengay

@itzzenxx that one has no PLAIN nor SHA-1

licaon-kter avatar Nov 22 '23 17:11 licaon-kter

I don't want to use PLAIN or SHA-1, I made those temporary modifications to see if that would fix CaaS's error response, but they didn't.
