+== Attachment Permissions
+
+Attachment permissions are handled by `LegacyAttachmentPolicy`, and unlike the permissions discussed so far, the permissions provided by `LegacyAttachmentPolicy` are not directly granted. Rather, the ability to create, view and delete attachments is determined by the attachment's parent realm and permissions the user possesses for that realm.
+
+The attachment actions are determined by the following
+permissions in the ticket, wiki and milestone realms:
+{{{#!table class="listing"
+||= Granted By: =||= Ticket =||= Wiki =||= Milestone =||
+|| `ATTACHMENT_CREATE` || `TICKET_APPEND` || `WIKI_MODIFY` || `MILESTONE_MODIFY` ||
+|| `ATTACHMENT_VIEW` || `TICKET_VIEW` || `WIKI_VIEW` || `MILESTONE_VIEW` ||
+|| `ATTACHMENT_DELETE` || `TICKET_ADMIN` || `WIKI_DELETE` || `MILESTONE_DELETE` ||
+}}}
+
+If explicit attachment permissions are preferred, `ATTACHMENT_CREATE`, `ATTACHMENT_DELETE` and `ATTACHMENT_VIEW` can be created using the [trac:ExtraPermissionsProvider]. The simplest implementation is to simply define the actions.
+{{{#!ini
+[extra-permissions]
+_perms = ATTACHMENT_CREATE, ATTACHMENT_DELETE, ATTACHMENT_VIEW
+}}}
+
+An alternative configuration adds an `ATTACHMENT_ADMIN` meta-permission that grants the other 3 permission.
+{{{#!ini
+[extra-permissions]
+ATTACHMENT_ADMIN = ATTACHMENT_CREATE, ATTACHMENT_DELETE, ATTACHMENT_VIEW
+}}}
+
+The explicit permissions can be used in concert with `LegacyAttachmentPolicy`, or `LegacyAttachmentPolicy` can be removed from `permission_policies`, in which case only users that have been explicitly granted the corresponding attachment actions will be able to create, delete and view attachments.
