What types of authentication does CDI work with?

RSA SecureID (built in, no need for ACE server connection), Password and ID, Challenge Response Token, Password and ID/ encryption, Full AES encryption. CDI recommends setting up your HEAD END devices for TACACS+ or Active Directory and then setting your remote device to “Device Authentication”. This will authenticate the user at the HEAD END and the device will automatically authenticate with each other from the HEAD END to the remote.
