You can use the Sun WBEM SDK APIs to set access control on a namespace or on a per-user basis. The following security classes are stored in the root\security namespace:
Solaris_Acl - Base class for Solaris Access Control Lists (ACL). 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 on individual users to the CIM objects within a namespace by creating an instance of the Solaris_UserACL class and then using the APIs to change the access rights for that instance. Similarly, you can set access control on namespaces by creating an instance of the Solaris_NameSpaceACL class and then using APIs, such as the setInstance method, to set the access rights for that instance.
An effective way to combine the use of these two classes is to first use the Solaris_NameSpaceACL class to restrict access to all users to the objects in a namespace. Then use the Solaris_UserACL class to grant selected users access to the namespace.
The Solaris_UserAcl class extends the Solaris_Acl base class, from which it inherits the string property capability with a default value r (read only).
You can set the capability property to any of the following values for access privileges.
Access Right | Description |
---|---|
r |
Read |
rw |
Read and Write |
w |
Write |
none |
No access |
The Solaris_UserAcl class defines the following two key properties. Only one instance of the namespace-username ACL pair can exist in a namespace.
Property | Data Type | Purpose |
---|---|---|
nspace |
string |
Identifies the namespace to which this ACL applies. |
username |
string |
Identifies the user to which this ACL applies. |
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, "root", "root_password"); // Get the Solaris_UserAcl class cimclass = cc.getClass(new CIMObjectPath("Solaris_UserAcl"); // Create a new instance of the Solaris_UserAcl class ci = cimclass.newInstance(); ...
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")); ...
Update the instance. For example:
... // Pass the updated instance to the CIM Object Manager cc.setInstance(new CIMObjectPath(), ci); ...
The Solaris_NamespaceAcl extends the Solaris_Acl base class, from which it inherits the string property capability with a default value r (read-only for GUEST and all users). The Solaris_NamespaceAcl class defines the following key property.
Property | Data Type | Purpose |
---|---|---|
nspace |
string |
Identifies the namespace to which this access control list applies. Only one instance of the namespace ACL can exist in a namespace. |
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, "root", "root_password"); // Get the Solaris_namespaceAcl class cimclass = cc.getClass(new CIMObjectPath("Solaris_namespaceAcl"); // Create a new instance of the Solaris_namespaceAcl class ci = cimclass.newInstance(); ...
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")); ...
Update the instance. For example:
// Pass the updated instance to the CIM Object Manager cc.setInstance(new CIMObjectPath(), ci);
