Single Sign On

This chapter provides information about the single sign on feature which allows end users to log into a Windows client machine on a Windows domain, then use certain Cisco Unified Communications Manager applications without signing on again.

For more information about the single sign on feature, refer to the Cisco white paper A complete guide for installation, configuration and integration of CUCM8.5 with Open Access Manager and Active Directory for SSO.

Configure Single Sign On

The single sign on feature allows end users to log into a Windows client machine, then use certain Cisco Unified Communications Manager applications without signing on again.

Perform the following steps to configure single sign on in your network.

For information about configuring single sign on with Cisco Unified Communication interface for Microsoft Office Communicator, refer to the Cisco Unified Communication interface for Microsoft Office Communicator documentation.

Procedure
    Step 1   Ensure that your environment meets the requirements.
    Step 2   Provision the OpenAM server in Active Directory, then generate keytab files.
    Note   

    If your Windows version does not include the ktpass tool for generating keytab files, then you must obtain it separately.

    Step 3   Import the OpenAM server certificate into the Cisco Unified Communications Manager tomcat-trust store.
    Note   

    You can not access any web applications if you do not import the OpenAM server certificate while enabling SSO.

    Step 4   Configure Windows single sign on with Active Directory and OpenAM.
    Step 5   (For Cisco Unified Administration only) Verify that the user is provisioned in the Active Directory.
    Step 6   (For Cisco Unified Administration only) Synchronize the user data to the Cisco Unified Communications Manager database using the DirSync service.
    Step 7   (For Cisco Unified Administration only) Add the user to the CCM Super Users group to enable access to Cisco Unified Administration.
    Step 8   Configure client browsers for single sign on.
    Step 9   Enable single sign on in Cisco Unified Communications Manager.

    Single Sign On for CUCM feature

    The single sign on feature allows end users to log into Windows, then use the following Cisco Unified Communications Manager applications without signing on again:

    • User Options
    • Cisco Unified Communications Manager Administration
    • Real-Time Monitoring Tool (RTMT) Administration
    • Cisco Unified Communication interface for Microsoft Office Communicator

    System requirements for Single Sign On

    The following single sign on system requirements exist for Cisco Unified Communications Manager:

    • Cisco Unified Communications Manager release 8.5(1) on each server in the cluster

    The feature requires the following third-party applications:

    • Microsoft Windows Server 2003 or Microsoft Windows Server 2008
    • Microsoft Active Directory
    • ForgeRock Open Access Manager (OpenAM) version 9.0

    The single sign on feature uses Active Directory and OpenAM in combination to provide single sign on access to client applications.

    These third party products must meet the following configuration requirements:

    • 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 Single Sign On

    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 Single Sign On.

    Configure Single Sign On

    This section provides information to configure single sign on.


    Tip

    Before you configure single sign on, review the configuration summary task for this feature.
