Table of Contents
dCache includes support for Access Control Lists (ACLs). This support is conforming to the NFS version 4 Protocol specification.
This chapter provides some background information and details on configuring dCache to use ACLs and how to administer the resulting system.
ACLs and pnfs
      ACLs are only supported with the Chimera name space
      backend. Versions before 1.9.12 had partial support for ACLs
      with the pnfs backend, however due to the limitations of that
      implementation ACLs were practically useless with pnfs.
