SAML SSO Open Access Manager Identity Provider on Linux Platform Configuration

First Published: Oct 23, 2014

Last Updated: Aug 31, 2017

Introduction

Single sign-on (SSO) is a session or user authentication process that enables a user to provide credentials to access one or more applications. The process authenticates the user for all applications they have been given rights to and eliminates further prompts when they switch applications during a particular session.

This document describes a SAML SSO configuration example. It provides steps used in the Cisco Collaboration Systems test bed to configure Open Access Manager (OpenAM) 10.0.1 as Identity Provider (IdP) on a Linux platform, and integrate OpenAM with Cisco Unified Communications Manager (Unified CM), Cisco Unified Communications Manager IM and Presence Service (IM and Presence Service), Cisco Unity Connection, and Cisco Prime Collaboration Assurance to enable SAML SSO.

For more information about the SAML SSO Solution and generic configuration directions, see: SAML SSO Deployment Guide for Cisco Unified Communications Applications.

Test Bed Details

In the Cisco Collaboration Systems test bed, Unified CM, IM and Presence Service, Cisco Unity Connection, and Cisco Prime Collaboration Assurance servers were configured for SAML SSO for administrator and user accounts to allow users to sign in to any of these servers in the organization without needing to re-enter credentials repeatedly. The test environment had the following characteristics:

■        Active Directory was used as the LDAP directory service when importing and authorizing users.

■        Users were synchronized from AD using the "sAMAccountName" attribute in Active Directory.

■        OpenAM 10.0.1 was set up on a Linux platform to authenticate users through username and password authentication.

■        Per node SSO was configured as opposed to cluster wide SSO.

o    NOTE: In per node SSO, metadata for each node is imported into the SSO IdP. In cluster wide SSO, introduced in Unified CM 11.5, the administrator configures a multi-server Tomcat certificate on the cluster, and a single metadata file can then be loaded onto the IdP for the entire cluster. For more information, see: Configure Single SAML IdP Connection/Agreement per Cluster with AD FS Version 2.0. Although this document is for AD FS, the process for setting up Unified CM is the same.

■        OpenAM was configured with proper data stores to authenticate users using Microsoft AD.

■        The OpenAM test certificate was used for signing SAML assertions.

Configuration

This section provides the high-level tasks and related information used to configure the Cisco Collaboration Systems test bed with OpenAM as an Identity Provider on the Linux platform, and to integrate OpenAM with Unified CM, IM and Presence Service, Cisco Unity Connection, or Cisco Prime Assurance to enable SAML SSO.

■        Configure User Data Store in OpenAM

■        Configure OpenAM as IdP on Linux Platform

■        Export Metadata From OpenAM

■        Enable SSO on Cisco Unified Communications Applications

Tip: For SAML SSO to work, the Cisco Unified Communications application and the IdP clocks must be synchronized.

Configure User Data Store in OpenAM

In Unified CM, IM and Presence Service, Cisco Unity Connection and Cisco Prime Collaboration deployments, users are added in the LDAP server and are synced to both the Cisco Unified Communications application and the IdP.

Configure OpenAM as IdP on Linux Platform

Prerequisites

■        Configure an LDAP-synchronized user with administrator privileges on the respective Cisco Unified Communications application server. For more information, refer to "LDAP Integration" in the product documentation. The user synced from Active Directory must have Standard CCM Admin User or Standard CCM Super User access roles assigned.

■        Download the SP Metadata XML files for your respective Cisco Unified Communications application servers. Download a .zip file with an SP XML file for each node in the cluster.

o    Unified CM and IM and Presence Service: Using a web browser, sign in to Unified CM as administrator, navigate to System > SAML Single Sign On, and click Export all Metadata.

o    Cisco Unity Connection: Using a web browser, sign in to Cisco Unity Connection as administrator, navigate to System Settings > SAML Single Sign On, and click Export all Metadata.

o    Cisco Prime Collaboration Assurance: Using a web browser, sign in to Prime Collaboration Assurance as globaladmin, navigate to Administration > System Setup > Single Sign On, and click Export all Metadata.

■       Use the XML files contained in this .zip in the following Step 4.

Tip: For large deployments, change OpenAM maximum sessions to 100000.

In the OpenAM server user interface, select Configuration > Servers and Sites > Default Server Settings> Session and under Session Limits change Maximum Sessions to 100000.

Export Metadata from OpenAM

When you enable SSO on the Cisco application server, you are asked to provide the IdP’s metadata file.

Enable SSO on Cisco Unified Communications Applications

When you have configured the IdP appropriately, enable SSO.
