2. Edit /etc/nsswitch.conf so the hosts line indicates the correct order for checking DNS information: hosts dns files Alternative goal: Configure the machine to first use local DNS information (/etc/hosts) before checking DNS. 1. Configure the machine to check /etc/hosts before looking to DNS. Edit /etc/nsswitch.conf so the hosts line indicates the correct order for checking DNS information: hosts files dns 2. Enter appropriate DNS information in /etc/hosts: webseal1.fully.qualified.com 1.11.111.111 webseal2.fully.qualified.com 2.22.222.222 The following general Windows-specific information is provided only as an example: 1. Use DNS and specify 2 IP addresses: Network Connections > LAN > Properties > TCP/IP 2. Specify a valid DNS server under the Advanced settings: Network Connections > LAN > Properties > TCP/IP > Advanced > DNS > Add... 3. In this same window, specify the primary DNS suffix for this connection: Network Connections > LAN > Properties > TCP/IP > Advanced > DNS > Add... 4. In your system properties, specify the computer name and its DNS suffix: My Computer > Properties > Network ID > Properties > Computer name My Computer > Properties > Network ID > Properties > More > Primary DNS suffix CDSSO configuration summary The following configuration steps are explained in detail in the remaining sections of this CDSSO chapter division. Configuring default CDSSO token create functionality 1. Enable WebSEAL to generate CDSSO tokens (cdsso-create). 2. Configure the built-in single sign-on authentication mechanism (library) for token create (sso-create). 3. Create the key file used to encode and decode the token. Copy the key file to all appropriate participating servers ([cdsso-peers] stanza). 4. Configure the token time stamp (authtoken-lifetime) 5. Configure the token label parameter (cdsso-argument). Configuring default CDSSO token consume functionality 1. Enable WebSEAL to consume CDSSO tokens (cdsso-auth) for authentication. 2. Configure the built-in single sign-on authentication mechanism (library) for token consume (sso-consume). 3. Assign the appropriate key file ([cdsso-peers] stanza). 4. Configure the token time stamp (authtoken-lifetime) 5. Configure the token label parameter (cdsso-argument). 248 IBM Tivoli Access Manager for e-business: WebSEAL Administration Guide
1. Enabling and disabling CDSSO authentication To enable CDSSO authentication, specify values for two settings in the WebSEAL configuration file. There is a setting for the token create (sso-create) library and a separate setting for the token consume (sso-consume) library. To enable the token create library, set the following entry: [cdsso] cdsso-create = {none|http|https|both} The value both specifies both HTTP and HTTPS protocols. The value none disables the token create library. To enable the token consume library, (this means that the server will accept CDSSO tokens for authentication) set the following entry: [cdsso] cdsso-auth = {none|http|https|both} The value both specifies both HTTP and HTTPS protocols. The value none disables the token consume library. Note: You must stop and restart the WebSEAL server in order to activate changes to the WebSEAL configuration file. Complete all of the applicable configuration steps in this section and then restart WebSEAL. 2. Configuring the single sign-on authentication mechanism The default CDSSO configuration requires that you enable the sso-create and sso-consume single sign-on authentication mechanisms. The sso-create mechanism is required by the initial WebSEAL server for creating the CDSSO token and building the redirected request. The sso-consume mechanism is required by the receiving WebSEAL server to decode the token and build the user credentials from the identity information contained in the token. For the default CDSSO configuration, each parameter specifies a built-in CDSSO token library file. One library contains the code for the token create functionality and the other library contains the code for the token consume functionality. v On UNIX, the library files are called libssocreate. {so | a | sl} and libssoconsume. {so | a | sl}. v On Windows, the library files are DLL files called ssocreate.dll and ssoconsume.dll. Authentication Mechanism Single Sign-on Token Library Solaris AIX Windows HP-UX sso-create libssocreate.so libssocreate.a ssocreate.dll libssocreate.sl sso-consume libssoconsume.so libssoconsume.a ssoconsume.dll libssoconsume.sl You can configure the CDSSO authentication mechanism by specifying the sso-create and sso-consume parameters with the full path name of the appropriate platform-specific default library file in the [authentication-mechanism] stanza of the WebSEAL configuration file. For example: Solaris: Chapter 9. Client single sign-on solutions 249
