PuTTY Release Notes (Server Suite 2022)

About this Release

PuTTY is a popular open-source client on Windows and UNIX-based computers that provides access to remote machines using well-known network protocols such as Telnet, SSH, rlogin and raw TCP. However, it does not support Kerberos authentication.

Delinea has enhanced PuTTY so that user authentication can be accomplished using Kerberos before establishing a remote connection. The Delinea-enhanced version of PuTTY takes advantage of the Kerberos environment that the Delinea DirectControl agent sets up automatically on managed UNIX and Linux computers. By using the Delinea PuTTY client to access Delinea-managed computer, you gain the benefits of centralized authentication and password policy enforcement using a secure and well-established authentication infrastructure.

Delinea PuTTY is currently integrated with open-source PuTTY version 0.75.
