Hello,
I created a repository to give you a taste on how user management and RBAC can be implemented. It works currently without authentication. I had it working with streamlit-ldap-authenticator, but disabled it in this repo because it does not work with a free ldap.forumsys.com free ldap server. It seems to work only with active directory based ldap servers. However, for the demo its not important.
The demo uses an in memory sqlite database. Datamodel and quick setup using docker is explained in the README.
The purpose is to give you an idea how something like this can be implemented using casbin and only 2 database tables.
Repo link: GitHub - kaizen63/streamlit-usermanager-demo
cheers
