Dear Emmanuel

Our Apache DS sever produces a huge amount of warnings with the following
message

undefined filter based on undefined attributeType not evaluted at all.
Returning empty enumeration.

29.10.2019 08:17:44,796 WARN  [pool-6-thread-15719]
org.apache.directory.server.core.normalization.NormalizationInterceptor.search():294
    - undefined filter based on undefined attributeType not evaluted at
all.  Returning empty enumeration.

it looks like this in code

// Normalize the filter
filter = ( ExprNode ) filter.accept( normVisitor );

if ( filter == null )
{
line 294:    LOG.warn( "undefined filter based on undefined
attributeType not evaluted at all.  Returning empty enumeration." );
    return new EntryFilteringCursorImpl( new EmptyCursor<Entry>(),
searchContext, schemaManager );
}

Is it possible to find out without debugging, why
FilterNormalizingVisitor returns null

from normalizeValue method?


With Best Regards
