Deployment Guide
If the expression evaluates to true, the AccessReject() will cause authorization to be refused. If the
expression evaluates to false, the AccessReject() is not called, and authorization process will continue
(however, the attribute will not be included in the Access-Accept, as the condition expression has evaluated
to false).
EnableDebug()
EnableDebug($flag = 1)
Enables debugging for the remainder of the processing of this request. The flag may also be set to false or 0
to disable debugging.
Example usage as part of a condition expression for an attribute:
return EnableDebug() &&
expression
When debugging is enabled, additional output is generated.
This may be visible in the RADIUS Debugger, or
in the application log.
DisableDebug()
DisableDebug()
Disables debugging; equivalent to
EnableDebug(0)
.
GetAttr()
GetAttr($attr_name)
Returns the value of an attribute supplied with the RADIUS Access-Request. The
$attr_name
argument is
the name of the attribute to look up. The attribute name is not case-sensitive. If the attribute was not
included with the Access-Request, returns NULL.
Example usage:
As a condition expression for an attribute:
return GetAttr('Calling-Station-Id') == '00-01-02-44-55-66'
As an attribute value:
<?= GetAttr('Calling-Station-Id')
ShowAttr()
ShowAttr($raw = false)
Show the attributes passed with the RADIUS Access-Request. Writes to stderr, so the output can be seen
using the RADIUS Debugger. The
$raw
argument, if set, outputs results without translating attribute
names. This function is useful to see exactly what a NAS is sending, if debugging an authorization problem.
Example usage:
return ShowAttr() && ... // rest of condition
MacAddr()
MacAddr($mac)
Converts a MAC address to a canonical form. Uses standard IEEE 802 form for the MAC address, that is,
uppercase hexadecimal digits using hyphen separators (01-23-45-67-89-AB). This function accepts anything
that can be interpreted as a MAC address using some fairly liberal guidelines and returns the address in
IEEE 802 format as described above. If a match could not be made (for example, empty string, or a string
not containing a valid MAC address), returns NULL.
