# SAIF.Business.Security.SystemUser dependencies

`SAIF.Business.Security.SystemUser` depends on SAIF framework packages for security context and configuration reading, plus two repository-local binaries for Active Directory access and encryption.

## Internal dependencies

| Dependency | Reference Type | Usage |
| --- | --- | --- |
| `SAIF.BOF.Framework` | NuGet Package | Supplies `SAIF.BOF.Framework.Security.clsSecurityPrincipal` for authentication state, domain inspection, and `IsInRole(...)` checks. |
| `SAIF.Framework.Common` | NuGet Package | Supplies `clsProperties` for reading `PROPERTIES.XML` and `OnlineProperties.xml`. |
| `SAIF.HashUtil` | NuGet Package | Declared package dependency with no direct source usage confirmed in the analysis findings.** |
| `SAIF.Web.API.Clients` | NuGet Package | Declared package dependency with no direct source usage confirmed in the analysis findings.** |
| `SAIFDirectorySvc.dll` | Internal local binary | Provides `SAIF.DirectoryServices` types used for user lookup, CRUD, and group management. |
| `SAIFEncrypt.dll` | Internal local binary | Provides `clsSecureEncrypt.EncryptString()` for payment-password comparison. |

## External dependencies
| Dependency | Version | Usage |
| --- | --- | --- |
| `Oracle.ManagedDataAccess` | Referenced in `packages.config` | Present for provider registration or transitive framework needs, but no Oracle calls are made by this library.* |
| `System.DirectoryServices` | .NET Framework assembly | Supports `DirectoryEntry` password updates, commits, and deletes used by the directory-service layer. |
| `System.Xml` | .NET Framework assembly | Supports XML configuration access performed through `clsProperties` and XML node handling. |

## Dependency risks and notes
- Local binary dependencies hide their internal implementation details, so LDAP host resolution and encryption design remain opaque.**
- This library has no `<ProjectReference>` dependencies on other source projects in the repository.
- Package references to `SAIF.HashUtil` and `SAIF.Web.API.Clients` may be transitive or packaging-related rather than directly invoked by library code.**
- Oracle provider registration exists without any matching SQL or data-access behavior in this library.*
