addServer()

Auth_RADIUS::addServer	(		$servername = 'localhost',
			$port = 0,
			$sharedSecret = 'testing123',
			$timeout = 3,
			$maxtries = 3
	)

Adds a RADIUS server to the list of servers for requests.

At most 10 servers may be specified. When multiple servers are given, they are tried in round-robin fashion until a valid response is received

public

Parameters

string	$servername	Servername or IP-Address
integer	$port	Portnumber
string	$sharedSecret	Shared secret
integer	$timeout	Timeout for each request
integer	$maxtries	Max. retries for each request

Returns

void

Calling this method is always a good idea, because all security relevant attributes are filled with Nullbytes to leave nothing in the mem.

getAttributes()

Auth_RADIUS::getAttributes

(

)

Reads all received attributes after sending the request.

This methods stores known attributes in the property attributes, all attributes (including known attibutes) are stored in rawAttributes or rawVendorAttributes. NOTE: call this function also even if the request was rejected, because the Server returns usualy an errormessage

Returns

bool true on success, false on error
