You may have noticed that the value of an attribute may differ, when you search it (when you add it as column), from the value displayed in the object. For example the search displays ‘True’ while attribute in the object displays ‘False’.
This only happens when searching for constructed attributes (i.e. edsva-MsExch), but not for stored attributes.
This is by design. ARS does not support the search of constructed attributes, which means that search results for those will always display ‘True’ regardless the real value of the constructed attribute.
An enhancement request (TF00462929) has been created detailing the feature.
The product team will evaluate the request and this feature may become available on a future release of the product.
