I want to set up a system on a ModX site whereby my client can upload and protect folders and documents, then issue usernames and passwords so clients can login and access them. My plan is to use a 3rd party user authentication PHP/MySql script to do this, however is there anything about ModX that might prevent this from working? My concern comes from a feature whereby I can protect folders using CPanel which works on every site I manage except the one that has ModX. Any suggestions? Thanks
