[Bug 2030747] Re: Port creation on shared network fails with port_security defined
Hello Roman:
This is the default security policy for non-admin users. By default, a
non-admin user cannot create a port defining the flags "--disable-port-
security" or "--enable-port-security". A non-admin user must create a
port with "--enable-port-security" implicitly defined.
To avoid this default rule, you can change your Neutron policy file, adding a rule similar to the "create_port" one:
"create_port:port_security_enabled": "(rule:admin_only) or (role:member and project_id:%(project_id)s)"
Take in mind that this is a potential security issue because you are
allowing non-admin users to create ports without any security.
I'm closing this bug.
Regards.

OpenStack deployment: kolla-ansible 2023.1
Neutron version is reported as
ubuntu@os:~$ docker exec neutron_server neutron --version
neutron CLI is deprecated and will be removed in the Z cycle. Use openstack CLI instead.

When user tries to create port on shared network, operation fails when option
[--enable-port-security | --disable-port-security]
is specified. If not, port created successfully with port_security_enabled = True
