Hi
I configured an ISDN link between a RouteAbout Access EI and a CISCO Router.
CHAP is used for authentication.
If the RA-EI dials to the Cisco the CHAP authentication faild. The RA sends a
'Authenticate Success' but the Cisco respons with an 'Authentication Failure'
!
Tested with RA Version V2.0-3, V2.0-2 and V2.0-1.
Is there anything misconfigured or is it a bug in the RA-EI or Cisco Code ?
Thanks for any help
Andreas

| 877.1 | Check cisco config...again! | MARVIN::TURNER | Neil Turner IPEG REO, 830-4140 | Mon Apr 28 1997 10:39 | 12 |
| I'm not sure exactly whats wrong but it looks to me like the cisco uses the Remote
ID field (cross8 in this case) from the RA-EI's chap response packet as a
'username' in order to locate the correct password. The message,
PPP Serial0:18 Unable to validate CHAP response. Username cross8 not found
implies to me that no username cross8 has been configured. (Or perhaps it is case
sensitive...cross8 is lower case).
Any cisco PPP CHAP expertise out there?

Thanks for your answer and sorry for my delayed answer.
The solution for their (SAP/CISCO) problem was to set the remote CHAP ID
to KMBCHAP (instead of cross8) on our RA90EI !
CHAP Ids/Passwords
-----------------
Local ID: KMBCHAP
Local Password: NEWTON
Remote ID: KMBCHAP
Remote Password: NEWTON
Thanks Andreas
