Where is PAP protocol used?
PAP is a password Authentication Protocol used by PPP links to validate users. PAP authentication requires the calling device to enter the username and password. If the credentials match with the local database of the called device or in the remote AAA database then it is allowed to access otherwise denied.
What form of authentication is password based authentication?
Simple password authentication offers an easy way of authenticating users. In password authentication, the user must supply a password for each server, and the administrator must keep track of the name and password for each user, typically on separate servers.
What is Shiva Password Authentication Protocol?
Shiva Password Authentication Protocol (SPAP) is a reversible encryption mechanism employed by Shiva. A computer running Windows XP Professional, when connecting to a Shiva LAN Rover, uses SPAP, as does a Shiva client that connects to a server running Routing and Remote Access.
Which is better CHAP or PAP?
CHAP is a stronger authentication method than PAP, because the secret is not transmitted over the link, and because it provides protection against repeated attacks during the life of the link. As a result, if both PAP and CHAP authentication are enabled, CHAP authentication is always performed first.
What does a basic auth header look like?
Basic Auth: The client sends HTTP requests with the Authorization header that contains the word Basic, followed by a space and a base64-encoded(non-encrypted) string username: password. For example, to authorize as username / Pa$$w0rd the client would send. Prefer to use HTTPS in conjunction with Basic Authentication.
What is the difference between PAP and SPAP?
Shiva Password Authentication Protocol (SPAP) SPAP is Shiva’s extended version of PAP and is slightly more secure. This protocol is included for use with legacy devices and systems that require it. Encrypted authentication (CHAP) CHAP is a standard protocol that uses encryption to prevent password snooping.
What is the difference between PAP and CHAP?
PAP is a password-based authentication protocol used by Point to Point Protocol (PPP) to validate users. In contrast, CHAP is a communication protocol that authenticates a user or network host to an authenticating entity. Thus, this is the main difference between PAP and CHAP.
How does password based authentication work in a server?

How is Password Authentication Protocol ( PAP ) used?
PAP is a password Authentication Protocol used by PPP links to validate users. PAP authentication requires the calling device to enter the username and password. If the credentials match with the local database of the called device or in the remote AAA database then it is allowed to access otherwise denied. The password is sent in clear text.
How does the Password Authentication Protocol ( CHAP ) work?
CHAP can provide authentication periodically to recognise that the user accessing the PPP link is same or not. In CHAP, the real passwords are never shared on the link instead a hash value of it is calculated and transferred.
How is password authentication performed in LDAP server?
In Figure 5–1, password authentication is performed in the following steps. The user enters a name and password. For the LDAP bind to Directory Server, the client application must bind with a Distinguished Name. Therefore the client application may use the name entered by the user to retrieve the DN.
