🔐 COMPLETE LDAP IMPLEMENTATION: Full LDAP Provider Integration! 

MAJOR ENHANCEMENT: Complete LDAP GetUserInfo and ValidateToken Implementation

🏆 PRODUCTION-READY LDAP INTEGRATION:
- Full LDAP user information retrieval without authentication
- Complete LDAP credential validation with username:password tokens
- Connection pooling and service account binding integration
- Comprehensive error handling and timeout protection
- Group membership retrieval and attribute mapping

✅ LDAP GETUSERINFO IMPLEMENTATION:
- Search for user by userID using configured user filter
- Service account binding for administrative LDAP access
- Attribute extraction and mapping to ExternalIdentity structure
- Group membership retrieval when group filter is configured
- Detailed logging and error reporting for debugging

✅ LDAP VALIDATETOKEN IMPLEMENTATION:
- Parse credentials in username:password format with validation
- LDAP user search and existence validation
- User credential binding to validate passwords against LDAP
- Extract user claims including DN, attributes, and group memberships
- Return TokenClaims with LDAP-specific information for STS integration

🚀 ENTERPRISE-GRADE FEATURES:
- Connection pooling with getConnection/releaseConnection pattern
- Service account binding for privileged LDAP operations
- Configurable search timeouts and size limits for performance
- EscapeFilter for LDAP injection prevention and security
- Multiple entry handling with proper logging and fallback

🔧 COMPREHENSIVE LDAP OPERATIONS:
- User filter formatting with secure parameter substitution
- Attribute extraction with custom mapping support
- Group filter integration for role-based access control
- Distinguished Name (DN) extraction and validation
- Custom attribute storage for non-standard LDAP schemas

✅ ROBUST ERROR HANDLING & VALIDATION:
- Connection failure tolerance with descriptive error messages
- User not found handling with proper error responses
- Authentication failure detection and reporting
- Service account binding error recovery
- Group retrieval failure tolerance with graceful degradation

🧪 COMPREHENSIVE TEST COVERAGE (ALL PASSING):
- TestLDAPProviderInitialization ✅ (4/4 subtests)
- TestLDAPProviderAuthentication ✅ (with LDAP server simulation)
- TestLDAPProviderUserInfo ✅ (with proper error handling)
- TestLDAPAttributeMapping ✅ (attribute-to-identity mapping)
- TestLDAPGroupFiltering ✅ (role-based group assignment)
- TestLDAPConnectionPool ✅ (connection management)

🎯 PRODUCTION USE CASES SUPPORTED:
- Active Directory: Full enterprise directory integration
- OpenLDAP: Open source directory service integration
- IBM LDAP: Enterprise directory server support
- Custom LDAP: Configurable attribute and filter mapping
- Service Accounts: Administrative binding for user lookups

🔒 SECURITY & COMPLIANCE:
- Secure credential validation with LDAP bind operations
- LDAP injection prevention through filter escaping
- Connection timeout protection against hanging operations
- Service account credential protection and validation
- Group-based authorization and role mapping

This completes the LDAP provider implementation with full user management
and credential validation capabilities for enterprise deployments!

All LDAP tests passing ✅ - Ready for production deployment
