createUserForbidden on OIDC enabled instance

Seems this tools doesn't work for OIDC enabled Harbor instances, as the local user creation would be disabled, when on OIDC.

When we run perf prepare on OIDC enabled instance we get below error [Test projects gets created fine]:
INFO[0001] GoError: failed to create user user-001, error: [POST /users][403] createUserForbidden source=console

We use admin User, so its not the User permission issue, rather not allowed of local User creation apart from the default admin user, when OIDC is enabled.

Any suggestions or workaround please?

Start with the perf prepare flow that creates user-001 and reproduce the reported [POST /users][403] createUserForbidden error against an OIDC-enabled Harbor instance. Review how the existing admin user and project creation steps behave, then define a supported workaround or preparation path that completes without local-user creation being rejected.
