Using the Solaris WBEM SDK APIs to Set Access Control

You can use the WBEM SDK's application programming interfaces (SDK APIs) to set access control on a namespace or on a per-user basis. These security classes are stored in the root\security namespace:

• Solaris_Acl – Base class for Solaris access control lists (ACLs). This class defines the string property capability and sets its default value to r (read only).

• Solaris_UserAcl – Represents the access control that a user has to the CIM objects within the specified namespace.

• Solaris_NamespaceAcl – Represents the access control on a namespace.

You can set access control for individual users to the CIM objects within a namespace by creating an instance of the Solaris_UserACL class. Then use the APIs to change the access rights for that instance. Similarly, you can set access control for namespaces by first creating an instance of the Solaris_NameSpaceACL class. Then using APIs, such as the createInstance method, to set the access rights for that instance.

An effective way to combine the use of these two classes is to use the Solaris_NameSpaceACL class first to restrict access to all users to the objects in a namespace. Then, you can use the Solaris_UserACL class to grant selected users access to the namespace.

Solaris_UserAcl Class

The Solaris_UserAcl class inherits the string property capability with a default value r (read only) from theSolaris_Acl class.

You can set the capability property to any one of these values for access privileges.

The Solaris_UserAcl class defines the following two key properties. Only one instance of the namespace and user-name ACL pair can exist in a namespace.

How to Set Access Control for a User

1. Create an instance of the Solaris_UserAcl class.

   For example:

   ... 
   /* Create a namespace object initialized with root\security
   (name of namespace) on the local host. */
   
   CIMNameSpace cns = new CIMNameSpace("", "root\security");
   
   // Connect to the root\security namespace as root. 
   cc = new CIMClient(cns, user, user_passwd);
   
   // Get the Solaris_UserAcl class 
   cimclass = cc.getClass(new CIMObjectPath("Solaris_UserAcl");
   
   // Create a new instance of the Solaris_UserAcl
   class ci = cimclass.newInstance();
   ...

2. Set the capability property to the desired access rights.

   For example:

   ...
   /* Change the access rights (capability) to read/write for user Guest
   on objects in the root\molly namespace.*/
   ci.setProperty("capability", new CIMValue(new String("rw")); 
   ci.setProperty("nspace", new CIMValue(new String("root\molly")); 
   ci.setProperty("username", new CIMValue(new String("guest"));
   ...

3. Update the instance.

   For example:

   ...
   // Pass the updated instance to the CIM Object Manager 
   cc.createInstance(new CIMObjectPath(), ci);
   ... 

Solaris_NamespaceAcl Class

The Solaris_NamespaceAcl inherits the string property capability with a default value -r (read-only for all users) from the Solaris_Acl class. The Solaris_NamespaceAcl class defines this key property.

How to Set Access Control for a Namespace

1. Create an instance of the Solaris_namespaceAcl class.

   For example:

   ...
   /* Create a namespace object initialized with root\security
   (name of namespace) on the local host. */ 
   CIMNameSpace cns = new CIMNameSpace("", "root\security");
   
   // Connect to the root\security namespace as root.
   cc = new CIMClient(cns, user, user_passwd);
   
   // Get the Solaris_namespaceAcl class 
   cimclass = cc.getClass(new CIMObjectPath("Solaris_namespaceAcl");
   
   // Create a new instance of the Solaris_namespaceAcl 
   class ci = cimclass.newInstance();
   ...

2. Set the capability property to the desired access rights.

   For example:

   ...
   /* Change the access rights (capability) to read/write 
   to the root\molly namespace. */
   ci.setProperty("capability", new CIMValue(new String("rw")); 
   ci.setProperty("nspace", new CIMValue(new String("root\molly"));
   ...

3. Update the instance.

   For example:

   // Pass the updated instance to the CIM Object Manager 
   cc.createInstance(new CIMObjectPath(), ci);
