Is it a bug of my mistake?

Hi Techies,

 

We have disabled multi station logins in our system long time ago...But system is allowing me to login from multiple stations.

 

*When i check logoff other sessions--It will logoff other station sessions and allows me to login from current work station

*When i check terminate this login -- It will not allow me to login untill unless i have logged off from other active station

 

But when i press cntl and check on radio button -


surprising.....check is disappearing from the buttons and system is allowing me to login even i already there from different work station.

 

What would be the reason?

 

 

 

Regards,

Nick Loy

    Any update ?

     

    If system is allowing me to multi station logins, then what is the sense of the parameter login/disable_multi_gui_login with value 1?

      From the documentation:

      If this parameter is set to value 1, multiple dialog logons to

      (in the same client and under the same user name) are blocked by the system:

       

      When the system recognizes a multiple logon, it displays a dialog box with the

      options "Terminate the current sessions" or "Terminate this logon".

       

      As said, check if the parameter really is active:

      - tcode RZ11

      - enter the value login/disable_multi_gui_login and press enter

      - Check the field "Current value".

    have you STOP and Start the SAP after the profile parameter change?.. Whether the profile is activated?...

    I will say it is a interesting finding. Looks like a SAP bug.

    Just wondering to know if the logins to SAP are done from GUI / CItrix etc., with SSO configuration. Also have a look on USR41_MLD if these table is updating with counter.

    @Jayaprakash: Please read my post....we have configuted this parameter a long ago and we had n number of restarts after that

     

    @Thomas: Thanks for the input....the parameter is showing active with value 1

     

    I will say it is a interesting finding. Looks like a SAP bug.

     

    Yes...looks like......i am also trying to take input from SAP

     

    @BAIGSA: No it's not updating the table since a long time

      Please check note [618068 - Collective corrections: Login dialog box|https://service.sap.com/sap/support/notes/618068]

      If the note does not apply and you are able to repeat the same in another system,

      you should report it to SAP.

      During search for something else, I found this note (not a perfect match, but similar)

       

      1405065 - Multiple GUI login possible in case of license popup.

       

      Symptom

      In case the license of the system is going to expire soon you get a popup.

      If you logon several times before confirming this popup you can bypass the check on multiple GUI logins.

       

      Other terms

      login/disable_multi_gui_login

       

      Reason and Prerequisites

      Program error

       

      Solution

      Install a kernel with a patch level that corresponds to at least the patch level specified on the "SP Patch Level" tab page

       

      ^This would mean patch 232 for 7.00 kernel

    Hi Tomas,

     

    Thanks for the update...

     

    Please check note 618068 - Collective corrections: Login dialog box
    If the note does not apply and you are able to repeat the same in another system, 
    you should report it to SAP.

     

    We are running on 4.7 with latest patch sets...and i got a reply from SAP as below

     

    Unfortunately this behaviour of the SAPGUI is known and there is no

    solution available as of now.

     

    This is very strange and pretty thing to see the reply "there is no solution as of now"

     

    Solution
    Install a kernel with a patch level that corresponds to at least the patch level specified on the "SP Patch Level" tab page
    
    ^This would mean patch 232 for 7.00 kernel

     

    This is not possible as we are running on 640.....

     

     

    If i have enabled the parameter and following SAP recommendations, but my end user is expert and he is utilizing this misbehavior.....then what?

     

     

     

    Regards,

    Nick Loy

      I just wanted to give an example and used 7.00 as a reference.

      For 6.40, that would be kernel patch 327 (From May 2010).

       

      Anyway.

      SAP knows about the behavior (bug) and don't have any solution.

      So, at least they are working on it.

      This sounds like a SAP kernel bug so it should be easy to implement when it's solved.

       

      Until then, you can only wait.

       

      or...hrm...not nice but...

       

      Another twist could be to allow your expert user to logon multiple times (instead of fighting him/her).

      You can enter the user name in parameter login/multi_login_users

       

      Description of the format:

      List the user IDs separated by commas ",".

      Blanks before/between user names are not allowed!

       

      Correct:  login/multi_login_users=ALPHA,BETA,GAMMA,DELTA

      Incorrect:   login/multi_login_users= ALPHA, BETA,GAMMA , DELTA

       

      I know, this is not a solution, but I just try to come up with some ideas how to handle the situation.
