22.3.1. Adding a User

The API adds an existing directory service user to the Red Hat Enterprise Virtualization Manager database with a POST request to the users collection. The client-provided new user representation includes an embedded roles list with at least one initial role to assign to the user. For example, the following request assigns two initial roles to the user

Example 22.2. Adding a user from directory service and assigning two roles

POST /api/users HTTP/1.1
Content-Type: application/xml
Accept: application/xml

        <role id="00000000-0000-0000-0001-000000000003"/>
The new user is identified either by Red Hat Enterprise Virtualization Manager user ID or via the directory service user principal name (UPN). The user ID format reported from the directory service domain might be different to the expected Red Hat Enterprise Virtualization Manager format, such as in LDIF [5] , the ID has the opposite byte order and is base-64 encoded. Hence it is usually more convenient to refer to the new user by UPN.


The user exists in the directory service domain before it is added to the Red Hat Enterprise Virtualization Manager database. An API user has the option to query this domain through the domains collection prior to creation of the user.
Roles are identified either by name or ID. The example above shows both approaches.

22.3.2. Adding Roles to a User

Further roles are attached or detached with POST or DELETE requests to the roles sub-collection of an individual user. The example below illustrates how the API adds the RHEVMVDIUser role to the role assignments for a particular user.


The embedded user roles list of the user element is only used for the initial creation. All interactions post-creation with the user's role assignments go through the roles sub-collection.

Example 22.3. Adding roles to a user

POST /api/users/225f15cd-e891-434d-8262-a66808fcb9b1/roles HTTP/1.1
Content-Type: application/xml
Accept: application/xml
