Assigning users and groups to roles
You can assign users and groups to roles if you are using WebSphere® Application Server authorization for Java™ Platform, Enterprise Edition (Java EE) roles.
Before you begin
Before you perform this task:
- Secure the web applications and Enterprise JavaBeans (EJB) applications where new roles are created and assigned to web and enterprise bean resources.
- Create all the roles in your application.
- Verify that you have properly configured the user registry that contains the users that you want to assign. It is preferable to have security turned on with the user registry of your choice before beginning this process.
- Make sure that if you change anything in the security configuration you save the configuration and restart the server before the changes become effective. For example, enable security or change the user registry.
About this task
These steps are common for both installing an application and modifying an existing application. If the application contains roles, you see the Security role to user/group mapping link during application installation and also during application management, as a link in the Additional properties section.
- Access the administrative console.
Type http://localhost:port_number/ibm/console in a web browser.
- Click Applications > Application Types > WebSphere enterprise applications > application_name .
- Under Detail properties, click Security role to user/group
mapping. A list of all the roles that belong to this application is displayed. If the roles already have users, or if one of the special subjects, AllAuthenticatedUsers, AllAuthenticatedInTrustedRealms, or Everyone is assigned, they display here.
- To assign the special subjects, select either the Everyone or the All Authenticated in Application's Realm option for the appropriate roles.
- To assign users or groups, select the role. You can select multiple roles at the same time, if the same users or groups are assigned to all the roles.
- Click Look up users or Look up groups.
- You can search for appropriate users
and groups from the user registry or you can add a user/group role
mapping and not perform the search. You activate either of these options
by clicking Search. See the next steps for the appropriate option you require.
- Get the appropriate users and groups from the user registry Complete
the Limit and the Search string fields by clicking Search.
The Limit field limits the number of users that are obtained and displayed from the user registry. The pattern is a searchable pattern matching one or more users and groups. For example, user* lists users like user1, user2. A pattern of asterisk (*) indicates all users or groups.
Use the limit and the search strings cautiously so as not to overwhelm the user registry. When you use large user registries such as Lightweight Directory Access Protocol (LDAP) where information on thousands of users and groups resides, a search for a large number of users or groups can make the system slow and can make it fail. When more entries exist than requests for entries, a message is displayed. You can refine your search until you have the required list.
If the search string you are using has no matches, a NULL error message is displayed. This message is informational and does not necessarily indicate an error, as it is valid to have no entries matching your selected criteria.
- Add a user/group role mapping
Add a user/group role mapping by clicking Search. Add IdP realms to the list of inbound trusted realms. For each Identity provider that is used with your WebSphere Application Server service provider, you must grant inbound trust to all the realms that are used by the identity provider.
- Click .
- Click .
- Fill in the external realm name.
- Click and .Skip remaining steps.
- Select the users and groups to include as members of these roles from the Available field and click >> to add them to the roles.
- To remove existing users and groups, select them from the Selected field
and click <<. When removing existing users and groups from roles, use caution if those same roles are used as RunAs roles.
For example, if the user1 user is assigned to the role1 RunAs role and you try to remove the user1 user from the role1 role, the administrative console validation does not delete the user. A user can only be part of a RunAs role if the user is already in a role either directly or indirectly through a group. In this case, the user1 user is in the role1 role. For more information on the validation checks that are performed between RunAs role mapping and user and group mapping to roles, see Assigning users to RunAs roles.
- Click OK. If any validation problems exist between the role assignments and the RunAs role assignments, the changes are not committed and an error message that indicates the problem is displayed. If a problem exists, make sure that the user in the RunAs role is also a member of the regular role. If the regular role contains a group that contains the user in the RunAs role, make sure that the group is assigned to the role using the administrative console. Follow steps 4 and 5. Avoid using any process where the complete name of the group, host name, group name, or distinguished name (DN) is not used.
