Hmm, I don't know enough to give you a confident answer yet. The provided extracts do not mention the possibility of integrating SAML or LDAP protocols directly into Ory Kratos as plugins. However, Ory Kratos does support social sign-in providers and allows customization of the integration by defining the OAuth scopes Ory requests from the provider and by setting up custom data mappings ([source](
https://www.ory.sh/docs/kratos/social-signin/ory#additional-configuration)). For a more detailed understanding of how to integrate other protocols like SAML or LDAP with Ory Kratos, I would recommend checking the official Ory documentation or reaching out to the Ory community for more specific guidance.
