Kerberos is a network authentication protocol, which allows secure communication between clients and My webMethods Server over a non-secure network. It provides mutual authentication for clients and My webMethods Server. Kerberos authentication uses symmetric encryption and a trusted third party system (a key distribution center (KDC)) to validate identity.

My webMethods Server supports Kerberos authentication integrated with Windows authentication to provide SSO (Single Sign-On). That is, a valid My webMethods Server user, already authenticated by Windows, need not login again to access My webMethods Server.

To configure Kerberos authentication integrated with Windows authentication, see Configuring Kerberos Authentication.
