Assign permissions to the //anonymous// user to set privileges for anonymous/guest users. The parts of Trac that a user does not have privileges for will not be displayed in the navigation bar. 11 11 In addition to these privileges, users can be granted additional individual rights in effect when authenticated and logged into the system. All logged in users belong to the virtual group //authenticated//, which inherits permissions from //anonymous//. 12 12 13 13 == Graphical Admin Tab 14 14 15 To access this tab, a user must have one of the following permissions: `TRAC_ADMIN`, `PERMISSION_ADMIN`, `PERMISSION_GRANT`, `PERMISSION_REVOKE`.

Rather, the ability to create, view and delete attachments is determined by the attachment's parent realm and permissions that the user possesses for that realm. 100 101 The attachment actions are determined by the following permissions in the ticket, wiki and milestone realms: 102 {{{#!table class="listing" 103 ||= Granted By: =||= Ticket =||= Wiki =||= Milestone =|| 104 || `ATTACHMENT_CREATE` || `TICKET_APPEND` || `WIKI_MODIFY` || `MILESTONE_MODIFY` || 105 || `ATTACHMENT_VIEW` || `TICKET_VIEW` || `WIKI_VIEW` || `MILESTONE_VIEW` || 106 || `ATTACHMENT_DELETE` || `TICKET_ADMIN` || `WIKI_DELETE` || `MILESTONE_DELETE` || 107 }}} 108 109 An authenticated user can delete an attachment //they added// without possessing the permission that grants `ATTACHMENT_DELETE`. 110 111 If explicit attachment permissions are preferred, then `ATTACHMENT_CREATE`, `ATTACHMENT_DELETE` and `ATTACHMENT_VIEW` can be created using the [trac:ExtraPermissionsProvider]. The simplest implementation is to simply define the actions: 112 {{{#!ini 113 [extra-permissions] 114 _perms = ATTACHMENT_CREATE, ATTACHMENT_DELETE, ATTACHMENT_VIEW 115 }}} 116 117 An alternative configuration adds an `ATTACHMENT_ADMIN` meta-permission that grants the other 3 permissions: 118 {{{#!ini 119 [extra-permissions] 120 ATTACHMENT_ADMIN = ATTACHMENT_CREATE, ATTACHMENT_DELETE, ATTACHMENT_VIEW 121 }}} 122 123 The explicit permissions can be used in conjunction 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. 124 97 125 == Granting Privileges 98 126 99 You grant privileges to users using[TracAdmin trac-admin].
