TDD Refactoring: Clean up LDAP provider production code

Browse Source 
PROBLEM FIXED:
- LDAP provider had hardcoded test credentials ('testuser:testpass')
- Production code contained mock user data and authentication logic
- Methods returned fake test data instead of honest 'not implemented' errors

SOLUTION:
- Removed all test data and mock logic from production LDAPProvider
- Production methods now return proper 'not implemented yet' errors
- Created MockLDAPProvider with comprehensive test data isolation
- Added proper TODO comments explaining what needs real implementation

RESULTS:
- Clean separation: production code vs test utilities
- Tests fail appropriately when features aren't implemented
- Clear roadmap for implementing real LDAP integration
- Professional code that doesn't lie about capabilities

Next: Move to Phase 2 (STS implementation) of the Advanced IAM plan
