  Then you have to turn a reject into accept.  You can't assign IPs in an Access-Reject packet.

  And the server can't turn an Access-Reject into an Access-Accept.  You have to catch the error earlier in the process.

  None of that runs the IP pool module to assign IPs.

  That's the key.  Note also that the user *isn't* being rejected.  The user is unknown!

  In the "authorize" section, check for users who are not found:

authorize {
	if (notfound) {
		... assign users from a different pool ...
		accept # force authentication to succeed

  That should work.
