This major refactoring eliminates all session storage complexity and enables
true distributed operation without shared state. All session information is
now embedded directly into JWT tokens.
Key Changes:
Enhanced JWT Claims Structure:
- New STSSessionClaims struct with comprehensive session information
- Embedded role info, identity provider details, policies, and context
- Backward-compatible SessionInfo conversion methods
- Built-in validation and utility methods
Stateless Token Generator:
- Enhanced TokenGenerator with rich JWT claims support
- New GenerateJWTWithClaims method for comprehensive tokens
- Updated ValidateJWTWithClaims for full session extraction
- Maintains backward compatibility with existing methods
Completely Stateless STS Service:
- Removed SessionStore dependency entirely
- Updated all methods to be stateless JWT-only operations
- AssumeRoleWithWebIdentity embeds all session info in JWT
- AssumeRoleWithCredentials embeds all session info in JWT
- ValidateSessionToken extracts everything from JWT token
- RevokeSession now validates tokens but cannot truly revoke them
Updated Method Signatures:
- Removed filerAddress parameters from all STS methods
- Simplified AssumeRoleWithWebIdentity, AssumeRoleWithCredentials
- Simplified ValidateSessionToken, RevokeSession
- Simplified ExpireSessionForTesting
Benefits:
- True distributed compatibility without shared state
- Simplified architecture, no session storage layer
- Better performance, no database lookups
- Improved security with cryptographically signed tokens
- Perfect horizontal scaling
Notes:
- Stateless tokens cannot be revoked without blacklist
- Recommend short-lived tokens for security
- All tests updated and passing
- Backward compatibility maintained where possible
