    88In addition to the default permission policy described in this page, it is possible to activate additional permission policies by enabling plugins and listing them in [TracIni#trac-permission_policies-option "[trac] permission_policies"]. See TracFineGrainedPermissions for more details.
    99
    10 Non-authenticated users accessing the system are assigned the name //anonymous//. Assign permissions to the //anonymous// user to set privileges for anonymous/guest users. The parts of Trac that a user does not have privilege for will not be displayed in the navigation.
     10Non-authenticated users accessing the system are assigned the name //anonymous//. 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.
    1111In 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//.

    1313== Graphical Admin Tab
    1414
    15 To access this tab, a user must have one of the following permissions: `TRAC_ADMIN`, `PERMISSION_ADMIN`, `PERMISSION_GRANT`, `PERMISSION_REVOKE`. The permissions can be granted using the `trac-admin` command (more on `trac-admin` below):

    1717$ trac-admin /path/to/projenv permission add bob TRAC_ADMIN

    20 Then, the user `bob` will be able to see the Admin tab, and can access the permissions menu. This menu will allow you to perform all the following actions, but from the browser rather than requiring root access to the server. '''Use at least one lowercase character in user names, as all-uppercase names are reserved for permissions.'''

    3030== Available Privileges
    3131
    32 To enable all privileges for a user, use the `TRAC_ADMIN` permission. Having `TRAC_ADMIN` is like being `root` on a *NIX system: it will allow you to perform any operation.
    33 
    34 Otherwise, individual privileges can be assigned to users for the various different functional areas of Trac ('''note that the privilege names are case-sensitive'''):

     97== Attachment Permissions
     98
     99Attachment 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 that the user possesses for that realm.
     100
     101The 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
     109An authenticated user can delete an attachment //they added// without possessing the permission that grants `ATTACHMENT_DELETE`.
     110
     111If 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
     117An alternative configuration adds an `ATTACHMENT_ADMIN` meta-permission that grants the other 3 permissions:
     118{{{#!ini
     119[extra-permissions]
     120ATTACHMENT_ADMIN = ATTACHMENT_CREATE, ATTACHMENT_DELETE, ATTACHMENT_VIEW
     121}}}
     122
     123The 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
    97125== Granting Privileges
    98126
    99 You grant privileges to users using [TracAdmin trac-admin]. The current set of privileges can be listed with the following command:
     127Privileges are granted to users through [TracAdmin trac-admin]. The current set of privileges can be listed with the following command:
    100128{{{#!sh
    101129$ trac-admin /path/to/projenv permission list
     
    123151Any user who has logged in is also in the //authenticated// group.
    124152The //authenticated// group inherits permissions from the //anonymous// group.
    125 For example, if the //anonymous// group has permission WIKI_MODIFY,
    126 it is not necessary to add the WIKI_MODIFY permission to the //authenticated// group as well.
     153For example, if the //anonymous// group has permission `WIKI_MODIFY`, it is not necessary to add the `WIKI_MODIFY` permission to the //authenticated// group as well.
    127154
    128155Custom groups may be defined that inherit permissions from the two built-in groups.
     
    140167
    141168== Adding a New Group and Permissions
     169
    142170Permission groups can be created by assigning a user to a group you wish to create, then assign permissions to that group.
    143171
    144 The following will add ''bob'' to the new group called ''beta_testers'' and then will assign WIKI_ADMIN permissions to that group. (Thus, ''bob'' will inherit the WIKI_ADMIN permission)
     172The following will add ''bob'' to the new group called ''beta_testers'' and then will assign `WIKI_ADMIN` permissions to that group. Thus, ''bob'' will inherit the `WIKI_ADMIN` permission.
    145173{{{#!sh
    146174$ trac-admin /path/to/projenv permission add bob beta_testers
     
    150178== Removing Permissions
    151179
    152 Permissions can be removed using the 'remove' command. For example:
     180Permissions can be removed using the 'remove' command.
    153181
    154182This command will prevent the user ''bob'' from deleting reports:
     
    175203== Default Permissions
    176204
    177 By default on a new Trac installation, the //anonymous// user will have ''view'' access to everything in Trac, but will not be able to create or modify anything.
    178 On the other hand, the //authenticated// users will have the permissions to ''create and modify tickets and wiki pages''.
     205By default on a new Trac installation, the //anonymous// user has ''view'' access to everything in Trac, but is not able to create or modify anything.
     206The //authenticated// user has the permissions to ''create and modify tickets and wiki pages''.
