When both the client and server are located in the same Windows (NT or Active Directory) domain, it is possible to integrate Windows Domain logon to the SSH Tectia client/server solution. This means that when a user logs on to a Windows Domain, the user gets a "ticket" that can be used for authenticating the user to SSH Tectia Server. The authentication procedure is then non-interactive; the user is not prompted to enter a password when SSH Tectia Client or ConnectSecure are connecting to SSH Tectia Server.
GSSAPI authentication can also be used in a mixed Windows/Unix environment. On Unix, GSSAPI interoperates with standard Kerberos implementations that provide a GSSAPI mechanism.
Active Directory/Kerberos is used in the Windows 2000/2003 Domains.
