These third party products must meet the following configuration requirements: 2 OL

3 Install and Activate Active Directory must be deployed in a Windows domain-based network configuration, not just as an LDAP server. The OpenAM server must be accessible on the network to all client systems and the Active Directory server. The Active Directory (Domain Controller) server, Windows clients, Cisco Unified Communications Manager, and OpenAM must be in the same domain. DNS must be enabled in the domain. No third-party products may be installed on the Cisco Unified Communications Manager server. The clocks of all the entities participating in SSO must be synchronized See the third-party product documentation for more information about those products. Install and Activate After you install Cisco Unified Communications Manager 8.6(1), your network can support single sign-on if you perform the necessary configuration tasks. For information on configuration tasks that you must perform, see the Configure, on page 1. Configure This section provides information to configure single sign-on. Tip Before you configure single sign-on, review the configuration summary task for this feature. Related Topics Configure, on page 1 Configure OpenAM Perform the following tasks using OpenAM: Configure policies in OpenAM for the following: CUCM User and UDS web application Query Parameters Configure a J2EE Agent Profile for Policy Agent 3.0. Configure a Windows Desktop SSO login module instance. Configure Login Form URI and OpenAM Login URL for the PA. Disable local user profiles. OL

4 Import the OpenAM Certificate Into CUCM Import the OpenAM Certificate Into CUCM Because communication between Cisco Unified Communications Manager and OpenAM is secure, you must obtain the OpenAM security certificate and import it into the Cisco Unified Communications Manager tomcat-trust store. Configure the OpenAM certificate to be valid for five years. For information about importing certificates, see the Cisco Unified Communications Operating System Administration Guide. Configure Windows with Active Directory and OpenAM This section describes how to configure Windows single sign-on with Active Directory and OpenAM. This procedure allows Cisco Unified Communications Manager to authenticate with Active Directory. Procedure Step 1 Step 2 Step 3 Step 4 In Active Directory, create a new user with the OpenAM Enterprise host name (without the domain name) as the User ID (login name). Create keytab files on the Active Directory server. Export the keytab files to the OpenAM system. In OpenAM, create a new authentication module instance with the following configuration: The type is Windows Desktop SSO. The realm attributes are determined as follows: Service Principal: Enter the principal name that you used to create the keytab file. Keytab File Name: Enter the path where you imported the keytab file. Kerberos Realm: Enter the domain name. Kerberos Server Name: Enter the FQDN of the Active Directory server. Authentication level: Enter 22. Configure Client Browsers for This section describes how to configure client browsers to use single sign-on. To use single sign-on for a browser-based client application, you must configure the web browser. Configure Internet Explorer for The single sign-on feature supports Windows clients running Internet Explorer version 6.0 and higher. Do the following tasks to configure Internet Explorer to use single sign-on: Select the Integrated Windows Authentication option. 4 OL

5 Configure the SSO Application Create a custom security level configured as follows: Select the Automatic Logon Only in Intranet Zone option Select all of the options for sites. Add OpenAM to the local zone, if it not already added. Do the following tasks for Internet Explorer 8.0 running on Windows 7: Disable Protected Mode. Under registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\LSA\, add DWORD value SuppressExtendedProtection - 0x02. Configure FireFox for The single sign-on feature supports Windows clients running Firefox version 3.0 and higher. To configure Firefox to use single sign-on, enter the trusted domains and URLs that are permitted to engage in SPNEGO Authentication with the browser into the network.negotiate-auth.trusted-uris preference. Configure the SSO Application To configure SSO, click Cisco Unified OS Administration > Security > Single Sign On. Note SSO is supported only for End User accounts, such as Agent Flow or SAML. SSO is not supported for Application User accounts. This application is split into three components: Status Status Select Applications Server Settings A warning message displays indicating that the change in SSO settings causes Tomcat restart. The following error messages may display when enabling the SSO application: Invalid Open Access Manger (Open AM) server URL - This error message displays when you give and invalid OpenAM server URL. Invalid profile credentials - This error message displays when you give a wrong profile name or wrong profile password or both. Security trust error - This error message displays when the OpenAM certificate has not been imported. If you get any of the above error messages while enabling SSO, then the status changes to the above errors. Select Applications OL
