Thanks for the response Chad.

Configuration wasn't correct on the AS5400 (which I don't have access to, so
couldn't check the config), it was pointing to an old DHCP server which was
causing the error.

For troubleshooting we setup DHCP on the AS5400 and the connection worked
flawlessly. Pointed to the *correct* DHCP server and it connected

Now we're on our way to using LDAP for authentication. Wish us luck!!! :)

 Try debugging PPP on the AS side. You may also want to debug DHCP packets.
It has been a while, but I think that error refers to the client being
unable to obtain an IP address.
