You need to assign the Doc CAL to a document. Do this on the User Documents tab. When you select a document, there will be a tab on the right for Document CALs. Enter 1 for number of CALs allocated and be sure to check Allow dynamic CAL assignment. The next user to come in besides the already assigned CAL user will be assigned the Doc CAL for that document.
