    Without going too much into write-up, lets evaluate Oracle’s own implementation of Single Sign-On Server i.e.  https://login.oracle.com  (In use by application like OTN, Conference.. )

    Server Name & Identity Management Version

    If you check screen shot (Oracle’s Login Server i.e. https://login.oracle.com), you can figure out that

    • Login server (Single Sign-On Server) is using Oracle Identity Management (
    • This is deployed on server rexweb100.oracle.com (+ other middle tier in cluster) with enterprise manager console running on port 1810

    Oracle SSO Page


    Users details from OIDDAS

    Now login to Oracle’s DAS (Delegated Administrative Services) using https://login.oracle.com/oiddas  on top right of page click on Login page , you can login with your OTN (Oracle Technology Network) account or create new account (using yahoo, gmail or any valid email address)

    After login; click on Directory tab and from this screen any user could search for details of other user including their email address (Check screenshot) – Useful for spammers or marketing team to target email address directly

    SSO 4


    Partner Application in SSO Server

    To list all Partner Applications registered against login.oracle.com check URL https://login.oracle.com/sso 

    SSO 2

    sso 3


    Don’t you think Oracle should hide user details (specially “email address” attribute) from OIDDAS search screen ?

    If you are SSO/OIDDAS administrator, What would you do in DAS configuration to hide listing email address or protect other SSO details (leave your views as comments) ?

    Stay tuned to find out how to hide above information from users….
