The full path of the selected file or directory is shown at the top of the dialog box, followed by the
file/directory owner and user.
2. The Group or User names section contains the list of Access Control Entries (ACEs) for the file or
directory. Complete this section as follows:
• Click Change Owner to select a new owner from a list of users. You must have permission to
change the owner.
• Click Add to add a new user or group to the list of entries. The maximum number of entries is 64.
• Click Remove to remove a user or group from the list of entries. Once an entry is removed, its
default settings (inherited from its parent directory) are applied.
• Click Up or Down to move an entry within the list. See “About the Ordering of ACEs within
an ACL” in the ContentManager User’s Guide for information on how to order the entries.
3. The Allowed/Deny Permissions section shows the current permissions for the selected ACE.
Complete these settings as follows:
• First choose which type of action you want to apply (allow or deny) by selecting Allow or Deny
from the drop-down box on the right. Allow provides the user control of the checked permissions;
Deny prohibits the user control of the checked permissions.
• Select the permissions by clicking the corresponding check box.
• Click the Apply button to apply your settings and then click OK to confirm the changes that you
made.
Note the following ACL rules:
