Using sentry preferences it is possible to control access to persons in an Online installation. However, in an Online environment, preference caches are refreshed only every 10 minutes, see here. This means that any restriction of visibility implemented by sentry preferences becomes only effective within this time. Thus, a new person record is visible according to standard security for up to 10 minutes.
1. Is it possible to shorten the refresh time interval for Online customers to say 1 minute?
2. In an onsite installation, where can I set the refresh time interval?
