User and authority data is usually stored in files VFPPF06 and VFPPF07 on the server
The data about the users, their passwords, and their authorities to Framework objects (applications, business objects and commands) will usually be stored in files VFPPF06 and VFPPF07 in the data library of the LANSA partition that the Framework is running in. These are ordinary LANSA files so you can easily check whether user details have been stored on the server.
The administrator must be connected to the server at the time that the user details are saved.
