Architecture¶

ActiveDirectoryServiceProxy constructs the generated clsADServicesSoapClient directly from a BasicHttpBinding and a caller-supplied EndpointAddress, bypassing the two <client><endpoint> entries configured in app.config.

Proxy mechanism¶

Aspect	Finding
Mechanism	Service Reference (svcutil)
Proxy type	`SAIF.Services.Web.Proxies.ActiveDirectory.clsADServicesSoapClient`
Base type	`System.ServiceModel.ClientBase<SAIF.Services.Web.Proxies.ActiveDirectory.clsADServicesSoap>`
Contract type	`SAIF.Services.Web.Proxies.ActiveDirectory.clsADServicesSoap` (`internal`)
Constructed in	`ActiveDirectoryServiceProxy` constructor (`Services/SAIF.Services.Web.Proxies/ActiveDirectoryServiceProxy.cs:18-21`)
Binding configured in	Code — `new BasicHttpBinding()` with framework defaults
Address supplied by	Constructor argument `serviceUrl`, whose own origin is unresolved within this repository

Construction path¶

The following diagram visualizes how a call reaches the remote service.

    PROXY --> REMOTE["Remote service<br>clsADServices (ASMX)"]
    WRAP --> DISPOSE["Close() on Dispose,<br>no Abort() fallback"]

Hand-written wrapper¶

Field	Value
Type	`SAIF.Services.Web.Proxies.ActiveDirectoryServiceProxy`
Source	`Services/SAIF.Services.Web.Proxies/ActiveDirectoryServiceProxy.cs`
Visibility	`public`
Implements	`IDisposable`
Responsibility	Constructs the internal generated client from a caller-supplied URL, exposes four operations by name, and disposes the client
Proxy lifetime	Per wrapper instance

Configuration applied	Value	Source
Binding security mode	`BasicHttpSecurityMode.None` (default; not overridden)	`ActiveDirectoryServiceProxy.cs:19`
Transport client credential	None set*	`ActiveDirectoryServiceProxy.cs:19`
`MaxReceivedMessageSize`	65,536 bytes (framework default, not overridden)*	`ActiveDirectoryServiceProxy.cs:19`
`MaxBufferSize`	Framework default, not overridden*	`ActiveDirectoryServiceProxy.cs:19`
Timeouts	None set — binding defaults apply (1 min send/open/close, 10 min receive)*	`ActiveDirectoryServiceProxy.cs:19`

Endpoint resolution¶

Environment	Address	Resolved from	Changeable without a rebuild
All	Caller-supplied `serviceUrl`; the design-time (unused) configured value is `http://webqa/WebServices/ADWebService/clsADServices.asmx`	`Services/SAIF.Services.Web.Proxies/ActiveDirectoryServiceProxy.cs:14-16` (parameter origin unresolved**)	Yes — the caller who constructs `ActiveDirectoryServiceProxy` controls it, but this repository does not show who that caller is or how the URL reaches them

Lifetime and disposal¶

Aspect	Finding
Proxy lifetime	Per wrapper instance
Disposal	`Dispose()` calls `webService.Close()`, with no `try`/`catch` and no `Abort()` fallback
Faulted-channel handling	Not handled — if the channel is faulted, `Close()` throws `CommunicationObjectFaultedException` from `Dispose`, which can mask the original failure inside a `using` block*
Thread safety	Not determined from source

Integration points¶

System	Type	Purpose
`clsADServices`	ASMX web service reached through a WCF-style `ClientBase<T>` proxy	Printer lookup, cached authorization checks, and contact lookups delegated to Active Directory*
