E_ADS_PROPERTY_INVALID

E_ADS_PROPERTY_INVALID indicates that a property-related operation does not satisfy the ADSI method contract. The error reference specifically directs callers to verify parameters passed to the method; this is broader than the property being absent or unsupported.

Capture the method, property name, and value shape together

Log whether the failing operation is Get, GetEx, Put, or PutEx.
For PutEx, remember that ADSI expects a variant array even when updating a single value.
Compare the value representation with the ADSI attribute syntax mapped from the native directory syntax.

The ADSI modification API separates single/multi-value operations and stores changes in the client-side cache until SetInfo. A malformed value can therefore fail before a server-side schema commit. Keep this error distinct from E_ADS_SCHEMA_VIOLATION, which describes a directory schema rule rejected by the attempted action. The most useful trace includes the VARIANT type, array cardinality, ADSI attribute name, and object class.
