No. Read the Proxy Cache design paper. https://openldap.org/conf/odd-wien-2003/proceedings.html
Hi Howard,
Thanks for the reply. Are you referring to this PDF from the link you provided, https://openldap.org/conf/odd-wien-2003/apurva.pdf
I have read through it, and also read this paper https://www.openldap.org/pub/kapurva/proxycaching.pdf by the same author. In the paper it contains such sentence
"The implemented algorithm supports answering of positive queries (no NOT operator) having equality, ordering or substring assertions. The query containment algorithm ensures that the correct syntaxes and matching rules are applied when comparing two assertion values."
Do we have any plan to support the ! operator in the future, since there are a lots of scenarios that ! operator appears in the filter.
Thanks.
