Hi Team,
Whether we have any documentation on the difference between all the authentication types as mentioned in the subject of this post. Because, when I have gone through Appian documentation not able to get the difference clearly. Kindly guide me.

Hey there,
You're right that the distinctions can be a bit nuanced. Here’s a brief overview to help clarify:
LDAP: Direct authentication against your organization's directory (like Active Directory). Appian validates credentials internally via the LDAP server.
SAML: Enables Single Sign-On (SSO) through an identity provider (IdP). Appian trusts the IdP and does not handle credentials directly, just the authentication assertion.
OpenID Connect (OIDC): Also supports SSO but is based on OAuth 2.0. It allows token-based authentication, typically used with modern IdPs like Azure AD or Google. Useful for mobile or API-based scenarios.
PIEE Authentication: A specific SAML-based method used for integrations with DoD systems, especially in federal projects. It includes compliance with DoD CAC/PIV requirements.
