[e-community-domain-keys] dA.com = /abc/xyz/key.fileA-A dB.com =/abc/xyz/key.fileA-B dC.com =/abc/xyz/key.fileA-C In this example, key.fileA-A identifies the key file used between all of the servers in domainA. key.fileA-B identifies the key file used between domain A and domain B. key.fileA-C identifies the key file used between domain A and domain C. Each remote server needs to have a copy of the appropriate key file used by the MAS. To exchange tokens with the MAS (domain A), all servers in domain B require copies of key.fileA-B: [e-community-domain-keys] dA.com =/efg/hij/key.fileA-B To exchange tokens with the MAS (domain A), all servers in domain C require copies of key.fileA-C: [e-community-domain-keys] dA.com =/efg/hij/key.fileA-C Any servers in domain A which use authentication services provided by the MAS must have a copy of key.fileA-A: [e-community-domain-keys] dA.com =/efg/hij/key.fileA-A In this example, key.fileB-B identifies the key file used between all of the servers in domainB. Also, key.fileC-C identifies the key file used between all of the servers in domainC [e-community-domain-keys] dB.com =/efg/hij/key.fileB-B dC.com =/efg/hij/key.fileC-C 5. Configuring the ″vouch for″ token label name The authentication information used for a single sign-on transaction is placed in the redirected request as an encrypted token query string argument to the request. This token string requires a name, or label, to identify it. The label name uniquely identifies the request to the receiving WebSEAL server as a single sign-on request to be handled by the single sign-on token consume mechanism (library). You must configure this token label on both WebSEAL servers participating in the single sign-on functionality. To configure the token label, use the vf-argument parameter located in the [e-community-sso] stanza of the WebSEAL configuration file. For example (default): [e-community-sso] vf-argument = PD-VF See “e-community single sign-on” on page 431. 6. Specifying the master authentication server (MAS) You must specify which server machine in the e-community is to function as the master authentication server (MAS). You must also specify if a server machine is not the MAS. 268 IBM Tivoli Access Manager for e-business: WebSEAL Administration Guide
is-master-authn-server Use the is-master-authn-server parameter to specify whether a server is the MAS or not. Values include ″yes″ or ″no″. For example: [e-community-sso] is-master-authn-server = yes Multiple WebSEALs can be configured to act as master authentication servers and then placed behind a load balancer. In this scenario, the load balancer is ″recognized″ as the MAS by all other WebSEAL servers in the e-community. If the server you are configuring is not the MAS, use the master-authn-server to specify to this server the location of the MAS. master-authn-server If the is-master-authn-server parameter is set to ″no″, this parameter must be uncommented and specified. The parameter identifies the fully qualified domain name of the MAS. For example: [e-community-sso] master-authn-server = mas.dA.com Additionally, you can specify the HTTP and HTTPS listening ports used by the MAS if these port values are other than the default (port 80 for HTTP and port 4443 for HTTPS). master-http-port If e-community-sso-auth enables HTTP e-community authentication and the master authentication server listens for HTTP requests on a port other than the standard HTTP port (port 80), the master-http-port parameter identifies the non-standard port. This parameter is ignored if this server is the master authentication server. By default, this parameter is disabled. [e-community-sso] master-http-port = master-https-port If e-community-sso-auth enables HTTPS e-community authentication and the master authentication server listens for HTTPS requests on a port other than the standard HTTPS port (port 443), the master-http-port parameter identifies the non-standard port. This parameter is ignored if this server is the master authentication server. By default, this parameter is disabled. [e-community-sso] master-https-port = 7. Specifying the ″vouch for″ URL vf-url The vf-url parameter specifies the ″vouch for″ URL. The value must begin with a forward-slash (/). The default value is /pkmsvouchfor. Chapter 9.
