ADSL Authentication problem

[alaa.musa]

Dear Sir:

I have a problem with ADSL authentication , I user radius NT and My LNS router is Cisco 3660 has IOS version "c3660-js-mz.122-10.bin" the problem is suddenly the ADSL users can't login to when I made a debug for radius I saw that the radius server return message access reject , I check the radius software but there was no problem also the same radius I use for dialup users and there is no problem m why the problem happened only at ADSL radius , is there a special configuration for radius authentication or it could be IOS bug

Your advice is highly appreciated

It is unlikely, based upon provided information that you are encountering a bug.

If your radius server returns an access reject, then look to the radius server for the solution. Why is the radius server returning an access-reject? What is it rejecting it for? username/password invalid, missing attribute or incorrect value in a particular attribute?

Again, analyzing the radius server logs would be a good starting point here.

Best of luck,

Jeff
