Error description

  • When SAML Web Single Sign-on TAI is enabled, if the URL
    contains Accented or DBCS characters, the request is
    corrupted.  If a Wiki URL (with Accented or DBCS characters)
    is in a Notes doc, when clicked on, the characters are
    corrupted in Connections.

    *                      corrupt content that contains accented  *

    * RECOMMENDATION:  Install a fix pack that contains this       *

    ****************************************************************
    When the SAML Web Single Sign-on TAI receives an HTTP servlet
    request that has accented or DBCS characters, and then the
    application receives the request, the characters may be
    corrupted.
    Here is an example from a trace of a corrupted URL that should
    have been /test/entry/T ??t :
    [6/25/14 11:24:27:174 IST] 00000103 EJSWebCollabo 3    Request
    Context Path=/blogs, Servlet Path=, Path
    Info=/test/entry/T ??st
    

Problem conclusion

  • When an HTTP servlet request is received that has no encoding
    set, it will be read in by the SAML TAI with the system
    default character encoding.  If the content is not encoded
    the same character encoding as the system default, the result
    will not be what was intended.
    
    After the SAML TAI reads the content, the encoding in the
    HTTPServletRequest will be set to the default and cannot be
    reset by the application.
    
    The SAML Web Single Sign-on runtime is updated so that it can
    use a user-identified character encoding instead of the
    default character encoding on the HTTP request.
    
    The following TAI custom property is added:
    
    sso_<id>.sp.charEncoding
    
    Set this property to the character encoding that you want to
    use to override the setting in the HTTPServletRequest.  This
    property has no default.  An example setting is "UTF-8".
    
    The following TAI custom property is also added:
    
    sso_<id>.sp.disableDecodeURL
    
    Valid values are true and false.  The default value is false.
    
    This property performs the same function as the
    com.ibm.ws.security.web.saml.disableDecodeURL security custom
    property that was added in APAR PI09544.  When you use the
    com.ibm.ws.security.web.saml.disableDecodeURL security custom
    property it will apply to all configured SSO service providers.
    You can use sso_<id>.sp.disableDecodeURL to apply the setting
    to individual SSO service providers.
    
    
    The fix for this APAR is currently targeted for inclusion in fix
     pack 7.0.0.37, 8.0.0.10, and 8.5.5.4.  Please refer to the
