Hi, I'm using slapd 2.3.27 as a metadirectory with two external active directory servers and pcache overlay enabled. The pcache overlay is working ok, but when I do a non-anonymous search and slapd gets the results from local cache, it establishes a new connection to the external directory, tries to bind and then closes the connection. Altough I understand that this is the logical behaviour, I'm looking for some way to avoid this binding against the external directory if the results of the search are going to be obtained from slapd cache, in order to increase performance (in my scenario validating credentials for cached results is not a priority).
If that is not possible, i'd like to know if there is a way to make slapd stablish a permanent connection to the external directory with the purpose of doing those credentials validations (instead establishing a new tcp connection on every search).
Thank you in advance.
