E_ADS_SCHEMA_VIOLATION

E_ADS_SCHEMA_VIOLATION is a server/schema-level rejection, not merely an invalid COM argument. Active Directory schema rules determine which attributes a class may contain, their syntax and value behavior, and which values are required before a new object can be committed.

Validate the complete SetInfo batch against the object schema

Record the object class and every attribute changed in the local cache before SetInfo.
Check mandatory attributes for new objects and the ADSI/native syntax of each value.
Remember that Microsoft documents SetInfo batch behavior: if one attribute modification is not allowed, none of the grouped modifications are committed.

This atomic-looking batch behavior makes the failing attribute easy to misidentify if several properties are staged before one SetInfo. Reduce the update to the smallest reproducible attribute set and compare each property with the class schema. For multi-valued attributes, also verify whether the operation is append, delete, update, or clear and whether the value is supplied in the array form expected by PutEx.
