Detailed Description

SabreDAV ACL Plugin.

This plugin provides functionality to enforce ACL permissions. ACL is defined in RFC3744.

In addition it also provides support for the {DAV:}current-user-principal property, defined in RFC5397 and the {DAV:}expand-property report, as defined in RFC3253.

aclPrincipalPropSetReport()

Sabre\DAVACL\Plugin::aclPrincipalPropSetReport (   $path, Xml\Request\AclPrincipalPropSetReport  $report  )

protected

aclPrincipalPropSet REPORT

This method is responsible for handling the {DAV:}acl-principal-prop-set REPORT, as defined in:

https://tools.ietf.org/html/rfc3744#section-9.2

This REPORT allows a user to quickly fetch information about all principals specified in the access control list. Most commonly this is used to for example generate a UI with ACL rules, allowing you to show names for principals for every entry.

Parameters

string	$path
Xml\Request\AclPrincipalPropSetReport	$report

Returns

void

expandPropertyReport()

Sabre\DAVACL\Plugin::expandPropertyReport (   $path,   $report  )

protected

The expand-property report is defined in RFC3253 section 3.8.

This report is very similar to a standard PROPFIND. The difference is that it has the additional ability to look at properties containing a {DAV:}href element, follow that property and grab additional elements there.

Other rfc's, such as ACL rely on this report, so it made sense to put it in this plugin.

Parameters

string	$path

getSupportedPrivilegeSet()

Sabre\DAVACL\Plugin::getSupportedPrivilegeSet

(

$node

)

Returns a tree of supported privileges for a resource.

The returned array structure should be in this form:

[ [ 'privilege' => '{DAV:}read', 'abstract' => false, 'aggregates' => [] ] ]

Privileges can be nested using "aggregates". Doing so means that if you assign someone the aggregating privilege, all the sub-privileges will automatically be granted.

Marking a privilege as abstract means that the privilege cannot be directly assigned, but must be assigned via the parent privilege.

So a more complex version might look like this:

[ [ 'privilege' => '{DAV:}read', 'abstract' => false, 'aggregates' => [ [ 'privilege' => '{DAV:}read-acl', 'abstract' => false, 'aggregates' => [], ] ] ] ]

Parameters

string | INode

$node

Returns

array

principalMatchesPrincipal()

Sabre\DAVACL\Plugin::principalMatchesPrincipal	(		$checkPrincipal,
			$currentPrincipal = null
	)

Find out of a principal equals another principal.

This is a quick way to find out whether a principal URI is part of a group, or any subgroups.

The first argument is the principal URI you want to check against. For example the principal group, and the second argument is the principal of which you want to find out of it is the same as the first principal, or in a member of the first principal's group or subgroups.

So the arguments are not interchangeable. If principal A is in group B, passing 'B', 'A' will yield true, but 'A', 'B' is false.

If the second argument is not passed, we will use the current user principal.

Parameters

string	$checkPrincipal
string	$currentPrincipal

Returns

bool

Principal property search.

This method can search for principals matching certain values in properties.

This method will return a list of properties for the matched properties.

Parameters

array	$searchProperties	The properties to search on. This is a key-value list. The keys are property names, and the values the strings to match them on.
array	$requestedProperties	This is the list of properties to return for every match.
string	$collectionUri	The principal collection to search on. If this is ommitted, the standard principal collection-set will be used.
string	$test	"allof" to use AND to search the properties. 'anyof' for OR.

Returns

array This method returns an array structure similar to Sabre\DAV\Server::getPropertiesForPath. Returned properties are index by a HTTP status code.
