Security

The mmdelacl command may only be issued by the file or directory owner.

You may only issue the mmdelacl command from a node in the GPFS nodeset where the file system is mounted.

In an SP environment, verify the authentication method set for SP security services:

1. If your authentication method is set to compatibility, Kerberos authentication is required. Issue the k4init command.
2. If your authentication method is set to DCE, dce_login authentication is required.
3. If your authentication method is set to NONE/std, there must be an entry in the /etc/sysctl.mmcmd.acl file on every node in the nodeset for the root user at every other node in the nodeset.
