CHAP
Network Level Authentication is used to authenticate Clients and servers to the network in Windows XP. It is also used to establish a remote desktop connection.
There are different ways for a network to ensure the person is who he is suppose to be, ie. authenticate. The most common way is to ask for a user name and password for authentication. This is not set up by a service, but rather by the network administrator. He/she has permission to go into control panel/User Groups and set up the authentication process is for that software. Another way is by registering the MAC address of the computer in the network.
For this purpose a standardization body IETF is present. there you can find number of RFCs for authentication techniques and methods. you can also checkout ietf.org

NAC is a centralised method for controlling network security.It is based on the following procedures.Detect - Detection and identification of new devices connecting to the network Authenticate - Authentication of users and/or devices Assess - Assessment of end systems regarding their compliance and/or vulnerabilities Authorise - Authorisation to use the network based on the results of the authentication and the assessmentMonitor - Monitoring users and devices once they are connected to the network Contain - Quarantine problem end systems and/or users to prevent them from negatively impacting the overall network environmentRe-mediate - Re-mediation of problems with the end system and/or user
I think one is database server authentication, the other is operating system level authentication (could be at the network level).
L2TP is a tunneling protocol for an IP network. L2 data is transmitted over the network but has no encryption or authentication abilities. This type of protocol is usually paired with IPSec to provide encryption and authentication.
