How do ACLs work in the LFC or DPM Name Server ?


ACLs are standard POSIX ACLs.

For details, see man lfc-setacl or man dpns-setacl.

If a same file has several Logical File Names (LFNs), this file has :

  • a primary LFN,
  • secondary LFNs : they are implemented as symlinks, and have dummy 777 permissions.

When an LFN (primary or secondary) is accessed, the permissions/ACLs on the primary LFN are checked.


For support/help, contact (remove the NOSPAM !). Your ROC will help you, and contact the appropriate experts if needed.
