[Pharo-users] pharo application user identity

Hi, my seaside, zinc and pharo applications had held user information within the image or a db. That was enough since the users never needed access to local resources. Now I am in the need to allow uploaded and storage of data on the server"s harddrive or a NAS. I wonder how you guys solve identity related issues. I recognized a ldap implementation on smalltalkhub. Is there a documentation/example available on best practices regarding user directories and such? Or is it a better idea to replace seaside based user registrations with solutions like keycloak and implement a single-sign-on infrastructure? Thank you for any hint! Sebastian
