WindowsXP PC (async line). There are several types of users callin to that NAS –
Cisco routers using ISDN, async modem users who shouldnt be called back, and
now there should be async modem users who should be called back. This is why I
need per user AAA what is done using RADIUS. Below is RADIUS profile
configuration. <o:p></o:p></span></font></p>

accept”. As far as I know – it should be configured on group-async
interface, but if I do it – nobody is able to call-in in any manner (with
callback or without). „debug aaa authentication” says that user isn’t
authorized for callback and AAA procedure exits at that moment (or maybe I’m
not doin enough debugging, so Im missin something). <o:p></o:p></span></font></p>

anyone has got working configuration for callback? Any ideas what to debug? I
understand that there might be not enough information, if you need something
else to give some comments – I’ll do it </span></font><font size=2
