Even though the ServerPorts table has the correct ServerID from the Servers
Table listed and the exact ports that the NAS reports and again from the
Servers table -- I can see that the Servers Table simply assigns a number (6
in this case) to the Server field (in this case rtr3-beloit) and to the IP
address (in this case 206.253.56.124) -- I need to manually alter this (the
ServerID) in the ServerPorts table and make it the IP (Nas-Identifier)? I'm
sure this can't be so...

I have ran this script numerous times and it does not change any of the
ports in any way as they are exactly the same as reported by the NAS , as
reported in the Servers Table, as reported in the ServerPorts table, and
reported as well as in the Calls Table. They all report or coincide exactly.
Does the NAS Type have anything to do with it? It is a type 9 stated as a
Cisco 5200 but is actually a Cisco 2511, (the QuickStart folks said this
wouldn't make any difference and that Concurrency Control was a snap). Has
anyone else confirmed without a doubt that Concurrency Control works on any
NAS and not just with radlogin? I'm certain that this is just something
totally stupid that I can't seem to resolve. And gosh, it's taken me almost
3 months of tinkering to get this far! Which brings up another point,
(besides the "I'm an idiot" thing..), what if you have several NAS's in one
location, does that mean even if Concurrency Control worked, couldn't
someone simply dial into another NAS and bypass the Concurrency Control?
