how to check ldap attrib and take action on accounting start

[Tariq Rashid]

One of our systems uses a fairly basic freeradius system (based on freeradius 1.0.2). A simple LDAP databse is used to check that a password matches the supplied username. 

What is the recommended way to achieve the following:

	* upon receipt of accounting start check LDAP to see if an attribute has been set (possibly something like "seenLive").

	* if it is set then then take no special action, continue as normal

	* if it hasn't been set then do the following:
		- set the attribute so that no special action is taken in future
		- send a message to a specified server (possibly XML over tcp). this i suspect will be done by calling an executable? or should the python/C modules be used for this?


your experience or advice appreciated.
