Info

Step-up authentication levels. WebSEAL enables authenticated users to increase the authentication level by use of step-up authentication. This key=value pair specifies which step-up authentication levels are supported by this WebSEAL server. Do not specify an authentication level unless the authentication method is enabled. For example, you must enable either basic authentication or forms authentication before setting level = password. Enter a separate key=value pair for each supported level. This stanza entry is required. Default values: level = authenticated level = password Example: level = password [step-up] stanza verify-step-up-user = {yes|no} Enforces policy requiring that the identity of the user performing the step-up operation match the identity of the user that performed the original authentication operation. To enforce this policy, set the value to yes. This stanza entry is required. Default value: no Example: verify-step-up-user = yes [mpa] stanza mpa = {yes|no} Enables support for multiplexing proxy agents. This stanza entry is required. Default value: no Example: mpa = no 418 IBM Tivoli Access Manager for e-business: WebSEAL Administration Guide
Authentication libraries [authentication-mechanisms] stanza passwd-cdas = fully_qualified_path Fully qualified path for the library that implements a CDAS library for either basic authentication or forms authentication. This stanza entry is optional. There is no default value. passwd-ldap = fully_qualified_path Fully qualified path for a library that implements basic authentication with an LDAP user registry. This stanza entry is optional. There is no default value. Example (entered as one line): passwd-ldap = C:\PROGRA~1\Tivoli\POLICY~1\bin\ldapauthn.dll & -cfgfile [C:/Program Files/Tivoli/PDWeb/etc/webseald-default.conf] passwd-uraf = fully_qualified_path Fully qualified path for a library that implements basic authentication using the Tivoli Access Manager URAF interface to underlying user registry types. This stanza entry is optional. There is no default value. cert-ldap = fully_qualified_path Fully qualified path for a library that implements certificate authentication. This stanza entry is optional. The default value for the built-in library on Solaris is: /opt/PolicyDirector/lib/libcertauthn.so & -chgfile \ [/opt/pdweb/etc/webseal-default.conf] Example on Windows (entered as one continuous line): cert-ldap = C:\PROGRA~1\Tivoli\POLICY~1\bin\libcertauthn.dll & -cfgfile [C:/Program Files/Tivoli/PDWeb/etc/webseald-default.conf] token-cdas = fully_qualified_path Fully qualified path for a library that implements token authentication. This stanza entry is optional. There is no default value. cert-ssl = fully_qualified_path Fully qualified path for a library that implements certificate authentication. This stanza entry is optional. There is no default value. http-request = fully_qualified_path Appendix A. WebSEAL configuration file reference 419
