Not sure about what authentication and web services EBS or Siebel have, but here is what we are doing at the State of Minnesota for PeopleSoft and OBIEE single-signon (no LDAP or SSO server required).
Two web services in PeopleSoft are used for user authentication. One web service simply requires valid PeopleSoft username & password in web service request SOAP header. Second web services determines the username of the PeopleSoft PS_TOKEN cookie (cookie is hashed string which is unique to user’s current PeopleSoft browser session).
BI Presentation Server in configured for single signon to pass PS_TOKEN cookie to BI Server as :USER variable.
Users can also connect directly to BI Server using JDBC or ODBC by providing valid PeopleSoft username & password. JDBC/ODBC tool which sends PeopleSoft credentials to BI Server :USER and :PASSWORD variables.
BI Server initialization blocks execute PL/SQL functions which invoke web services using either the PS_TOKEN cookie from :USER or the PeopleSoft username & password from :USER and :PASSWORD.
A user can login in directly to BI Answers/Dashboards by including a valid PeopleSoft username & password in the nqUser & nqPassword parameters of the Analytics URL. This requires PeopleSoft credentials in URL which poses a security risk. Separate Presentation Server without single signon configuration could be used for direct access.
