> "Ranger User Sync" logs into Ranger multiple times a second. This is with:
> {code}
> ranger.usersync.source.impl.class=org.apache.ranger.unixusersync.process.UnixUserGroupBuilder
> ranger.usersync.unix.backend=nss
> {code}
> The high number and rate of these sessions makes it impossible to use the
> "Login Sessions" audit page:
> Further, it's adding a lot of extra requests and overhead to Ranger, Ranger
> User Sync, and the backing database (e.g. MySQL).
> *The service should re-use its session rather than continual logins.*
> !screenshot-1.png|width=640!
> {code}
> $ rpm -qa *usersync*
> ranger_2_6_4_0_91-usersync-0.7.0.2.6.4.0-91.x86_64
