- How long should nss_sss return cached entries before
- initiating an out-of-band cache refresh (0 disables
- this feature)
+ The entry cache can be set to automatically update
+ entries in the background if they are requested
+ beyond a percentage of the entry_cache_timeout
+ value for the domain.
+ </para>
+ <para>
+ For example, if the domain's entry_cache_timeout
+ is set to 30s and entry_cache_nowait_percentage is
+ set to 50 (percent), entries that come in after 15
+ seconds past the last cache update will be
+ returned immediately, but the SSSD will go and
+ update the cache on its own, so that future
+ requests will not need to block waiting for a
+ cache update.
+ </para>
+ <para>
+ Valid values for this option are 0-99 and
+ represent a percentage of the entry_cache_timeout
+ for each domain. For performance reasons, this
+ percentage will never reduce the nowait timeout to
+ less than 10 seconds.
