• Implement Identity Token service. It receives authentication result and issues identity token.
• Implement Authentication management facility.
• Implement LDAP/AD authentication login module, client can login using LDAP/AD account.
• Implement Kerberos authentication login module.
• Implement some web SSO login module, such as SAML2 login module.
