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?
