I am using Microsoft IAS for my 2950's and 3550's. So far I can only get it to work using PAP. The options available are CHAP, MS-CHAP, MS-CHAP2, PEAP, and MD5. Are any of these supported by cisco because PAP is not secure.
Check out the link below. I am using Microsoft Internet Authentication Servicec (IAS) to connect to a 3550 through telenet. I need to do this so that users can be authenticated through active directory. If you look half way down the document those are the protocols offered and only PAP seems to work. I am wondering why on an unencrypted protocol is used and if it is the same on a firewall too.
As far as encryption is concerned since you are using Radius the user password is encrypted between the device and IAS in the Radius packet. So we need not worry as long as the secret key is not known to anybody.
