The issue is resolved, apparently I didn’t have the required changes in local_settings.py in the keystone backend section. Zitat von Eugen Block <eblock@nde.ag>:

Hi *,

I have a fresh Victoria installation where the "create user" button is missing in the dashboard. Creating users via CLI works fine, also when I go to https://controller/identity/users/create I see the dialog to create a new user. I see the same in an Ussuri installation. The clouds are deployed manually (we have our own Salt mechanism) on baremetal, the OS is openSUSE Leap 15.2. What I have tried so far is to apply the keystonev3_policy.json from [1], but without success. There are no other custom policies applied, most configs are on default. There are no obvious errors in the dashboard logs, and before I change too much I wanted to ask for your advice. Can anyone help me out? Please let me know if you need more information.

Thanks in advance, Eugen
