CA SSO : How to resolve "Missing required cookies, exiting"

  • 1.  CA SSO : How to resolve "Missing required cookies, exiting"

    Posted 02-15-2018 02:38 AM

    Hi,

     

    I am working on setting up of new Siteminder platform. While testing an application with the basic authentication scheme, I am getting the below error

    “Missing required cookies, exiting”

     

    May I know how to troubleshoot this? I feel it is because of ACO settings and tried verifying the same.

    PFB ACO settings.

    RequireCookies=yes

    EnableCookieProvider=no

    CookieDomain=.abc.xyz

    CookieDomainScope=2

     

    Thanks.

     

    Regards,

    Hi Dliip, 

     

    Can you try accessing the application with FQDN and check if you are able to access the application,

    Hi Ram,

     

    Thanks for your quick response. Yes, you are correct. Getting the expected behavior on launching the application with FQDN.

     

    I remember that we can get the expected behavior(accessing application with localhost) using multi values in agent name parameter of ACO. I used the below syntax

    <agent_name(which should be used)>, <server_name/localhost/VIP/IP>:<port_number(if applicable)>

     

    But I am not getting the expected behavior. Do I need to make any other changes?

     

    Thanks.

     

    Regards,

    Dhilip

    Hi Dhilip,

     

    Check the value of ACO parameter - requirecookies 

     

    Set requirecookies=No and test.

     

    Refer : SiteMinder Browser Cookies - CA Single Sign-On - 12.52 SP1 - CA Technologies Documentation

    This should work with RequireCookies=YES.

    You have invalid configuration.

    You have set "CookieDomain=.abc.xyz"

    So, if even if you access resource using local host http://localhost/resource, web agent is going to set the cookie domain for the SMSESSION cookie to .abc.xyz.

     

    This cookie is NOT submitted by the browser when you then access http://localhost.

    You will need to have HOST only cookie for this to work.

    So , try commenting CookieDomain and CookieDomainScope params.

     

    You can verify this from fiddler.

    Hi Ujwol,

     

    Thanks for your response. I agree with your point.

     

    But, I remember that we were getting the expected behavior (protecting the application with server_name/VIP/IP/localhost) without commenting out CookieDomain/CookieDomainScope (while I was working in my previous organization). I am not sure if any server configurations were performed (we were using IIS webserver) but we were using multivalue for agent parameters(localhost is one among those). Currently, I am using apache webserver(in Windows OS), I hope this behavior is irrespective of webserver.

     

    1. I noticed the below lines in your response, I didn't understand clearly. Does this mean, we are using this agent to protect the application only using localhost?

          <<

          You will need to have HOST only cookie for this to work.

          >>

     

    2. Is there a way to achieve the expected behavior without commenting out CookieDomain/CookieDomainScope?

     

    Thanks.

    Dhilip

    Try 

    ForceCookieDomain=yes

    ForceFQHost=yes

    Hi Ujwol,

     

    I think ForceCookieDomain and ForceFQHost will be handy only if we use short name of the server (instead of FQDN) as I could see that localhost is getting redirected to localhost followed by domain name (In this case, localhost.abc.xyz) resulting in 'Page cannot be displayed'.

     

    Thanks.

    Then you are out of luck.

    Haha...  But, I am sure that it is possible to protect the application using localhost/IP/VIP/short name of the server/FQDN of the server as I have tested this configuration before but not sure about how it was implemented.
