[victorvhs017]

Add LDAP Authentication Support

Adds LDAP authentication method for machine identities, bringing Python SDK to feature parity with the Go SDK.

Changes

• Added LdapAuth class in infisical_sdk/resources/auth_methods/ldap_auth.py
• Registered LDAP auth in the Auth class

Usage

client = InfisicalSDKClient(host="http://localhost:8080")

    identity_id="your-identity-id",
    username="ldap-username",
    password="ldap-password"

Greptile Summary

Added LDAP authentication support for machine identities, following the established pattern used by other auth methods (UniversalAuth, OidcAuth, AWSAuth).

Changes:

• Created new LdapAuth class with login() method accepting identity_id, username, and password
• Registered LDAP auth in the main Auth class alongside existing methods
• Implementation correctly uses the InfisicalRequests wrapper and MachineIdentityLoginResponse model
• Code follows the exact same pattern as OidcAuth and UniversalAuth implementations

Review Notes:

• Implementation is clean, secure, and consistent with existing codebase patterns
• No security issues detected - credentials are sent via HTTPS POST to the API endpoint
• No breaking API changes introduced
• Check that external documentation has been updated for discoverability

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The implementation is clean, follows established patterns exactly, introduces no breaking changes, and adds straightforward LDAP authentication support. No security vulnerabilities or logical errors detected.
• No files require special attention
