Access Control Lists (ACLs)

This topic describes behavior of the ACL Rules (Access Control List Rules) object in Moab Web Services. It contains the URLs, request bodies, and responses delivered to and from MWS.

The Fields: Access Control Lists (ACLs) reference contains the type and description of all fields in the ACL Rules object. It also contains details regarding which fields are valid during PUT and POST actions.

Supported methods

ACLs are not directly manipulated through a single URL, but with sub-URLs of the other objects such as Virtual Containers and Reservations.

Resource	GET	PUT	POST	DELETE
/rest/reservations/<rsvId>/acl-rules/<aclId>	--	Create or Update ACL	--	Delete ACL
/rest/vcs/<vcId>/acl-rules/<aclId>	--	Create or Update ACL	--	Delete ACL

Getting ACLs

Although ACL Rules cannot be retrieved directly using the GET method on any of the acl-rules resources, ACL Rules are attached to supported objects when querying for them. Each supported object contains a field named aclRules, which is a collection of the ACL Rules defined on that object.

Supported objects

The following is a list of objects that will return ACL Rules when queried:

Creating or Updating ACLs

The HTTP PUT method is used to create or update ACL Rules. The request body can contain one or more ACL Rules. If an ACL Rule with the same type and value exists, then it will be overwritten.
