Left panel missing after LDAP sync

Infos:

  • Used Zammad version: 4.1.0
  • Used Zammad installation type: package and docker-compose
  • Operating system: Ubuntu 20.04.3 LTS
  • Browser + version: Chrome 93.0.4577.82 and Safari 14.1.1

Expected behavior:

  • We need users from LDAP as customers and agents.

Actual behavior:

  • The users were exported, the login works. But after that, the entire left panel disappears.

Steps to reproduce the behavior:

  • Go to System → Setting → Integrations → LDAP, make LDAP connection and mapping. Sync.

What are the users roles (and role permission)? ^^

Administrator accounts, including mine, have the Admin role. I don’t see anything in the left pane. The rest of the users fell into the Customer role.
I did not change the rights of the roles. I attach a screenshot of the Admin role rights.
