Obtain Security Information for a File within OpenEdition

To obtain security information for a file within OpenEdition, perform one of the following actions:

• Use the OpenMVS ISPF Shell.
• Enter the ls ‑l or ls ‑E shell command.
• Run a stat( ) or fstat( ) function in a program.

The system returns the following information:

• Type of file or directory
• Owner permission bits
• Group permission bits
• Other permission bits

If the system can locate the TSO/E user ID and CA Top Secret group name that correspond to the file’s UID and GID permission bits, the system displays the ID and group name. If the UID is 0, the system displays the user that owns the UID. For CA Top Secret, the owner is the MSCA ACID, in which case the display shows *MSCA* (not the MSCA ACID name).

If the system cannot find the corresponding TSO/E user ID and CA Top Secret group name, the system displays the UID and GID.
