Comment 32 for bug 2042744

guys the error occurs because of the permissions of keystone user
grep keystone /etc/passwd if this commands gives the result with something like this /usr/sbin/nologin or /bin/false then change it using usermod -s /bin/bash keystone after this install and configure within the keystone user or in root user also make sure the keystone user is not flagged as system account.
This helped me in setting the keystone i am using ubuntu 22.04.03 lts and openstack antelope
