Group based
In this design the users are split into groups and permissions are assigned to the group, not the individual user, as shown in Figure 3.
Figure 3 - a group-based permission system
This design has the following advantages:
Once the user has been identified the USER record will supply the USER-GROUP identity which is all that is needed to access the PERMISSIONS table.
Any change made to a group's permissions will automatically be inherited by all members of that group
Changes to a group's permissions can be made very easily as there is only one table, the PERMISSIONS table, to maintain.
If an individual user is switched to another group this will sever all connections to the permissions of the previous group and replace them with those of the new group.
In this design the USER-GROUP table is sometimes known as SECURITY-CLASS or ROLE.

A snippet from the man page for bash:
${parameter:offset:length}
Substring Expansion. Expands to up to length char-
acters of parameter, starting at offset. If length
is omitted, expands to the substring of parameter,
starting at the character specified by offset.
length and offset are arithmetic expressions (see
ARITHMETIC EVALUATION below). length must evaluate
to a number greater than or equal to zero. If off-
set evaluates to a number less than zero, the value
is used as an offset from the end of the value of
parameter. If parameter is @, the result is length
positional parameters beginning at offset. If
parameter is an array name indexed by @ or *, the
result is the length members of the array beginning
with ${parameter[offset]}. Substring indexing is
zero-based unless the positional parameters are
used, in which case the indexing starts at 1.

Note: This article was created based on Flex 2. Minor changes in the description and code may be necessary before it can be applied to Flex 3.
As a PHP and HTML developer you may be wondering, "How do I start using Flex?" Adobe Flex is a very powerful set of tools but "...with great power comes great responsibility."

DSM Plugins
Setting up the plugin (Quick Start)
Copy the plugin file into your UltraVnc directory. - The DSM file needs to be in the same directory as the vncviewer and winvnc programs. The plugins may be found in the "plugins" directory under your UltraVNC directory. If you don't find the plugins there, download them from this website and unzip them to your UltraVNC directory.
Generate a Key file. - Start the UltraVNC Viewer. Select the plugin from the list. Click on the Configure button. In the "Generate New Key File section, note the path and name of the key to be generated. (The default is "new_XXXX.key") If there is an option, Select the key size. Click on "Gen Key".
Distribute your key - Rename the new_XXXX.key file to XXXX.key. The XXXX.key file must be copied onto each machine that you will be using, both viewers and servers. Copy the key into your UltraVNC directory.
Enable the Plugin on the Server. - Open the VNC server's System Properties. Select the plugin from the list. Check the "Use the DSM Plugin" checkbox. Click on Apply, then OK. You will need to restart the WinVNC service before the plugin is properly enabled.
Enable the plugin on the Viewer. - Start the UltraVNC viewer. Select the plugin from the list. Check the Use the DSM Plugin checkbox. Click on Connect.
