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. tariq
