Storing files on the grid is one thing. Controlling access to these files is a different matter. This page is the result of an ongoing investigation on how to control access rights for different storage systems (currently: dCache and DPM), as well as the way a files is stored and accessed on the Local File Catalog (LFC).
Case #1: dCache
Creating your own directory in SRM-space
srmmkdir ....
Copying and registering your file
lcg-cr ....
Looking at the permissions
- SRM : srm-get-permissions
Modifying the permissions
- SRM : srm-set-permissions
Verifying access control
- SRM : srm-get-permissions
- Try to access the file as another user
Case #2: DPM
Creating your own directory in DPM-space
srmmkdir .... ?? dpns-mkdir
Copying and registering your file
lcg-cr ....
Looking at the permissions
- SRM : srm-get-permissions is broken
- dpns-getacl
Modifying the permissions
- SRM : dpns-setacl
Verifying access control
- SRM
- Try to access the file as another user
Case #3: LFC
Copying and registering your file
- lcg-cr .... with full path
- lcg-cr .... with generated path
Looking at the permissions
- lfc-getacl
- lfc-la
- lfc-lg
- lfc-lr
- lfc-ls
- lcg-gt
Modifying the permissions
- lfc-setacl
Verifying access control
- lfc-getacl
- lfc-la
- lfc-lg
- lfc-lr
- lfc-ls
- Try to access the file as another user
