When request a GetCapabilities with a user who have different roles (tested with 3, not admin) on the main wfs/wms URL (/geoserver/wfs), It took a very long time to generate the response (~10minutes).
If I set VERBOSE_MODE, I see in the log that for a single user, GeoFence seems to request LDAP for user and user's role a huge amount of time (cf attached file).
With tcpdump, I see a huge traffic on port 636 (ldaps) when requesting getcap document.
I think there is a huge problem with GeoFence access right checking as it took 10 minutes for a simple GetCapabilities.
