APAR status

  • Closed as program error.

Error description

  • During the DB2 instance creation at silent install time, if the
    user
    invokes the option to have DB2 to create Unix accounts, the
    accounts are created with a saved hashed password that uses the
    DES encryption method.  The accounts that DB2 install can create
    on behalf the user are: DB2 instance, DB2 Administrator Server
    (DAS) and Fenced ID. See Security Bulletin for details:
    http://www-01.ibm.com/support/docview.wss?uid=swg22012948
    

Local fix

  • The initial password hash uses a weak encryption which can be
    mitigated by changing the password after account creation.
