Five Things You Need to Know About Basic Framework Security
User and authority data is usually stored in files VFPPF06 and VFPPF07 on the server
Data in VFPPF06/07 controls access to Framework objects for both Web and Windows users
There are two sets of user profiles and passwords on the server
You can assign authorities to groups of users
In design mode security is not applied
Advanced Options
You can add your own extra layers of security checking
You can make the Framework validate user profiles and passwords using your own security system
You do not have to use Framework security
A user who signs on with one profile can be automatically changed to another
Two different Frameworks can share the same set of users
User and security data can be stored as an XML file instead of using files VFPPF06/07
You can store other information relating to a user
You can include the user profile and password in a start URL
Export or Import of Full or Partial User Data
How to Export User Data
How to Import User data from an XML file

Frequently Asked Questions (Users and Security)
I do my unit and suite testing in Design mode. Is this a good practice?
When I run the Framework security does not seem to work?
Why options I have disabled for Windows and/or the Web browser are displayed?
Why does a user with my user profile get automatically created?
What are the user timeout settings used for?
Can I control which user profile appears on the status bar?
How can my RDML programs access the user profile that the user signed on as, and the user profile shown in the status bar?
How can I allow the user to change their own password?
When I start the Framework as an administrator (for example UF_ADMIN), the Framework appears briefly and then disappears?
