Multiple AD servers for Scale CES

Currently, Spectrum Scale CES only supports the addition of a single AD server for SMB authentication. We have encountered a couple of events where a communication issue with that DC results in auth services on the CES node(s) going offline, requi...

Enable opt-in flush-on-close feature in GPFS
