  • 5 Ratings


  • Unable to reset the SSO admin password after upgrading to vCenter Server 5.1.0b
  • Attempting to reset the SSO admin password fails.
  • Running the rsautil reset-admin-password command fails
  • Setting the SSO password to a previously used password fails
  • You see the error:
ERROR: Key [com.rsa.db.msserverinstance] is not defined


This issue occurs if:
  • You try to reset the password that you have previously used. By default, you cannot use any of the last five passwords again.
  • The com.rsa.db.msserverinstance property is not updated in the file for SSO. 


To resolve this issue:
  • Ensure that you are using a new password.
  • Update the com.rsa.db.msserverinstance property in the file for Single Sign On:
    1. Open the file using a text editor.

      Note: By default, the file is located at:
      • vCenter Server installed on Windows – C:\Program Files\VMware\Infrastructure\SSOServer\webapps\ims\WEB-INF\classes\
      • For vCenter Server Appliance 5.1 – /usr/lib/vmware-sso/webapps/ims/WEB-INF/classes

    2. Add this entry to the file:


      Where instance is the RSA database name. The default instance name is: 

      • vCenter Server installed on Windows – com.rsa.db.msserverinstance=RSA
      • vCenter Server Appliance 5.1 – com.rsa.db.msserverinstance=ssodb
