IBM WebSphere Portal V8.5 wcmライブラリー・シンジケーション

Question

複数の仮想ポータルを持つAIX 7.1上でWebSphere Portalバージョン8.5クラスターを使用し、管理対象ページで作業し、各仮想ポータルには、独自のライブラリーと、そのライブラリを各VPに転送します。

シンジケータ（WASベースポータル）とサブスクライバ（仮想ポータル）の間のシンジケーションペアを正常に作成し、それらとすべての間のテスト済み接続が良好です（VPは同じサーバ上にローカルなので意味があります）。シンジケートにライブラリのコンテンツをしようとすると、しかし、それは順番待ちの状態にとどまるとのSystemOut.logに私は次のエラー・ログを参照してください。

WCM Syndication requires HTTP Basis Authentication to be configured and working. 

then I needed to make sure that Trust Association is enabled in WAS Console under Security -> Global Security -> Web and SIP security -> Trust association. 
confirmed that the box that says Enable trust association is checked. 
also ensured the Interceptor com.ibm.portal.auth.tai.HTTPBasicAuthTAI is created and the configuration were correct. 
the cause of the error was that in the fields of urlBlackList and urlWhiteList there was use of the variable ${WpsContextRootPath} which i found out that it is not set anywhere so i change it to /wps instead and now the fields are as follow: 
urlBlackList = /wps/myportal* 
urlWhiteList = /wps/mycontenthandler* 

after Restarting the server and retry syndication - it works!. 

also you may follow the direction in this link: 
https://developer.ibm.com/answers/questions/206675/why-do-i-see-occasionally-see-a-popup-box-with-a-t.html 

but setting these parameters disabled the servlet of vieweing all items in the libraries...
