+                    Consequently, the <filename>USERADD_ERROR_DYNAMIC</filename>
+                    variable is by default not set.
+                    If you plan on using statically assigned
+                    <filename>gid</filename> and <filename>uid</filename>
+                    values, you should set

+                    Overriding the default behavior implies you are going to
+                    also take steps to set static <filename>uid</filename> and
+                    <filename>gid</filename> values through use of the
