E_ADS_OBJECT_UNBOUND
E_ADS_OBJECT_UNBOUND reflects ADSI object lifecycle rather than a missing attribute. ADSI can hold local object/cache state, but methods that require the underlying directory resource need a valid binding. Microsoft specifically calls out newly created objects and the SetInfo/GetInfo sequence.
Re-establish remote state before reading server-backed properties
- Record whether the object was obtained by binding to an existing ADsPath or created through a container interface.
- For a newly created object, commit required attributes with
SetInfobefore expecting all remote-backed operations to behave like an existing bound entry. - After commit, use
GetInfowhen a fresh server-backed property cache is required.
The ADSI cache model is important here: Put and PutEx can modify client-side cached values, while SetInfo commits them to the directory. A local object reference with cached changes is not evidence of a valid remote binding. When this error appears, log the creation/bind path and last successful SetInfo or GetInfo operation instead of repeatedly reading the same property.
