SPNEGO Kerberos Authentication

Agiloft supports single sign on via the Kerberos authentication protocols, using SPNEGO to access the knowledgebase via HTTP.

What are SPNEGO and Kerberos?

  • Kerberos is an a authentication protocol, which allows nodes communicating over a non-secure network to prove their identity to one another in a secure manner. It is designed to provide strong authentication for client/server applications by using secret-key cryptography.
  • SPNEGO, pronounced 'spang-go or spe-'nay-go, is a GSSAPI "pseudo mechanism" used by client-server software to negotiate the choice of security technology. SPNEGO is used when a client application wants to authenticate to a remote server, but neither end is sure what authentication protocols the other supports. Most notably used by browsers for HTTP negotiation.
  • For more information, see Kerberos and SPNEGO.

Prerequisites

To complete SPNEGO/Kerberos setup you must have:

  • A server environment configured with Kerberos/SPNEGO.
  • Agiloft must be installed on a machine in the Active Directory domain. 
  • A known address for the domain key distribution center (KDC).
    Note: the KDC address is often the same as the domain controller address. 
  • An account name and password in the domain to be used for pre-authentication.
  • A registered Service Principal Name (SPN) with the account mentioned above for all known names of a server where  Agiloft is installed. To register an SPN, run setspn.exe -A HTTP/<server> <account name> for all known names of a server where  Agiloft is installed. The command should be run on the domain controller.
