Zammad sends many GET requests to keycloak

Infos:

• Used Zammad version: 6.2.0
• Used Zammad installation type: source
• Operating system: Ubuntu Focal
• Browser + version: N/A

Expected behavior:

• Zammad sends only required requests to Keycloak

Actual behavior:

• I’m seeing a huge number of GET requests to https://keycloak.example.com/realms/realm/protocol/saml
  All of them are resulting in a “400 Bad Request”.

As those are GET requests, there’s no additional payload and no URL params set.

I’m not sure, if this is a bug or just a configuration issue, although there’s not much to configure to get SAML working.

Steps to reproduce the behavior:

• No idea, maybe setting up SAML with Keycloak is already enough?
