owser is Microsoft Internet Explorer. If this is the case, configure the browser to always check for newer versions of stored pages: Tools > Internet Options > General > Temporary Internet Files > Settings v Do not configure the MAS server on the same interface (IP address) of another participating WebSEAL server instance. v Because some WebSEAL configuration requires machine host names to be described as fully qualified host names, you must ensure that your system and network can resolve machine names into fully qualified host names. For example, using fully qualified host names allows for many host names (IP addresses) per machine, as in the case of multiple WebSEAL instances. Resolving machine names E-community can be disabled upon WebSEAL startup because the machine itself is not adequately configured to resolve machine names. The machine on which WebSEAL resides needs to be able to fully resolve an IP address. Because this functionality is very operating system-specific, it is not the role of this document to provide instructions. Always consult your system administrator if you are not sure your system has the proper capabilities. The following general Solaris-specific information is provided only as an example: Goal: Configure the machine to first look to DNS before checking the local /etc/hosts file for DNS information. 1. Make sure that /etc/resolv.conf has valid DNS server entries. 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 E-community configuration summary An e-community is configured under the following conditions and guidelines: 264 IBM Tivoli Access Manager for e-business: WebSEAL Administration Guide
v The ″vouch for″ server (the MAS or a delegated ″vouch for″ server) always has the token create responsibility v The receiving server (where the requested resource is located) always has the token consume responsibility v A delegated ″vouch for″ server (for all domains remote from the MAS domain) must have both token create and token consume capabilities The following configuration steps are explained in detail in the remaining sections of this e-community chapter division: Configuring default token create functionality on the ″vouch for″ server The following configuration steps are explained in detail in the remaining sections of this e-community chapter division. 1. Enable e-community authentication to process single sign-on requests by communication type (e-community-sso-auth). 2. Specify the unifying name of the e-community for all participating servers (e-community-name). 3. Configure the built-in single sign-on authentication mechanism (library) for token create (sso-create). 4. Create the key file used to encode and decode the ″vouch for″ token. Copy the key file to all appropriate participating servers ([e-community-domain-keys] stanza). 5. Configure the token label parameter used in the ″vouch for″ reply (vf-argument). 6. Specify if this server is the MAS or not the MAS (is-master-authn-server). 7. Specify the ″vouch for″ URL used in the ″vouch for″ request (vf-url). 8. Configure token and ec-cookie lifetime values (vf-token-lifetime and ec-cookie-lifetime). Configuring default token consume functionality on the receiving server The following configuration steps are explained in detail in the remaining sections of this e-community chapter division. 1. Enable e-community authentication to process single sign-on requests by communication type (e-community-sso-auth). 2. Specify the unifying name of the e-community for all participating servers (e-community-name). 3. Configure the built-in single sign-on authentication mechanism (library) for token consume (sso-consume). 4. Assign the appropriate key file ([e-community-domain-keys] stanza). 5. Configure the token label parameter used in the ″vouch for″ reply (vf-argument). 6. Specify that this server is not the MAS (is-master-authn-server). 7. Specify the ″vouch for″ URL used in the ″vouch for″ request (vf-url). 8. Configure token and ec-cookie lifetime values (vf-token-lifetime and ec-cookie-lifetime). Chapter 9.
