Zammad ADFS SAML 422: The change you wanted was rejected

Technical assistance
1

Zammad version: 6.0.0

Hello, we attempted to get Zammad working with SAML with our ADFS servers; here’s a list of things we attempted to do in order to make it work:

  • inputted the certificate both with and without -----BEGIN CERTIFICATE-----
  • tried using both the certificate and the certificate fingerprint
  • made sure the servers are all running UTC time
  • restarted the server after enabling the feature
  • confirmed it seems to resolve OK on the ADFS side

Error in the UI:

# 422: The change you wanted was rejected.

Message from saml: invalid_ticket

Here’s the error we get on the pod itself:

Hi @plupu. What’s written down in the Zammad log?

@fliebe92 this is what I get:

Is this an excerpt of your Zammad production.log?

5

It;s from the kubernetes pod log for zammad, I’m guessing that should have all the output? If you can direct me I can try to ssh into a specific container to check the logfile directly

6

I dug around a little through the containers but couldn’t find anything substantial:

$ pwd
/opt/zammad
$ cd log
$ pwd
/opt/zammad/log
$ cat production.log
I, [2023-07-18T14:57:38.823588#4418-6180]  INFO -- : Using Zammad's file store as Rails cache store.
I, [2023-07-18T14:57:38.823888#4418-6180]  INFO -- : Using the File back end for Zammad's web socket session store.
$ ls -l
total 4
-rw-r--r-- 1 zammad zammad 217 Jul 18 14:57 production.log

You can try to tail the log and see if it gets filled just by clicking around in Zammad. When the SAML login is performed and it fails, there should be a reason next to invalid_ticket (at least I remember to see it in former times).

This is all I get while doing a tail for the whole attempt:

Hm. I have no idea, sorry.

Docker based installation log to STDOUT. You’re looking for the stdout log output of the railsserver.
