Refer to SVN documentation for syntax of the authz file. Groups are
supported.
As the fine-grained permissions brought by this permission policy are
often used in complement of the other permission policies (like the
`DefaultPermissionPolicy`), there's no need to redefine all the
permissions here. Only additional rights or restrictions should be added.
=== Installation ===
Enabling this policy requires listing it in `trac.ini`::
{{{
[trac]
permission_policies = AuthzPolicy, DefaultPermissionPolicy
[authz_policy]
authz_file = conf/authzpolicy.conf
}}}
This means that the `AuthzPolicy` permissions will be checked first, and
only if no rule is found will the `DefaultPermissionPolicy` be used.
=== Configuration ===
The `authzpolicy.conf` file is a `.ini` style configuration file.
- Each section of the config is a glob pattern used to match against a
Trac resource descriptor. These descriptors are in the form::
{{{
<realm>:<id>@<version>[/<realm>:<id>@<version> ...]
}}}
Resources are ordered left to right, from parent to child. If any
component is inapplicable, `*` is substituted. If the version pattern is
not specified explicitely, all versions (`@*`) is added implicitly
Example: Match the WikiStart page::
{{{
[wiki:*]
[wiki:WikiStart*]
[wiki:WikiStart@*]
[wiki:WikiStart]
}}}
Example: Match the attachment
``wiki:WikiStart@117/attachment/FOO.JPG@*`` on WikiStart::
{{{
[wiki:*]
[wiki:WikiStart*]
[wiki:WikiStart@*]
[wiki:WikiStart@*/attachment/*]
[wiki:WikiStart@117/attachment/FOO.JPG]
}}}
- Sections are checked against the current Trac resource '''IN ORDER''' of
appearance in the configuration file. '''ORDER IS CRITICAL'''.
- Once a section matches, the current username is matched, '''IN ORDER''',
against the keys of the section. If a key is prefixed with a `@`, it is
treated as a group. If a key is prefixed with a `!`, the permission is
denied rather than granted. The username will match any of 'anonymous',
'authenticated', <username> or '*', using normal Trac permission rules.
Example configuration::
{{{
[groups]
administrators = athomas
[*/attachment:*]
* = WIKI_VIEW, TICKET_VIEW
[wiki:WikiStart@*]
@administrators = WIKI_ADMIN
anonymous = WIKI_VIEW
* = WIKI_VIEW
# Deny access to page templates
[wiki:PageTemplates/*]
* =
# Match everything else
[*]
@administrators = TRAC_ADMIN
anonymous = BROWSER_VIEW, CHANGESET_VIEW, FILE_VIEW, LOG_VIEW,
MILESTONE_VIEW, POLL_VIEW, REPORT_SQL_VIEW, REPORT_VIEW,
ROADMAP_VIEW, SEARCH_VIEW, TICKET_CREATE, TICKET_MODIFY,
TICKET_VIEW, TIMELINE_VIEW,
WIKI_CREATE, WIKI_MODIFY, WIKI_VIEW
# Give authenticated users some extra permissions
authenticated = REPO_SEARCH, XML_RPC
}}}
