## and its component services have been changed to use the new Delinea name and logo.

Feature Changes

  • A new parameter "<instance> " is added for DB2 group plug-in. By default, the group plug-in allow DB2 to get all Active Directory groups even if the Active Directory group is not visible in the zone. To optionally constrain the DB2 visibility to zone visible Active Directory groups only, set this parameter to true. (Ref: 469458)

Bugs Fixed

Known Issues

Known issues on UNIX/Linux

The following sections describe known issues or limitations associated with this release.

  • The DB2 username/password plug-in cannot authenticate any user when the machine is not joined to a zone or DirectControl agent is not running.

    The DB2 username/password plug-in uses a new way to authenticate local user, and this relies on the DirectControl agent. Therefore, if the machine is not joined or DirectControl agent is not running, the DB2 username/password does not work. (Ref: 64711).

Known issues on AIX

  • The single sign on can only work with Active Directory users.

    If you have an Active Directory user and local user with the same username and AIX is configured to use LAM, you may not be able to log in as an Active Directory user. If the user is not logged in as the Active Directory user, the DB2 GSSAPI plug-in for single sign on does not work. The DB2 GSSAPI plug-in only works with Active Directory user accounts. To ensure that single sign on always works, rename, or remove the local user account.

Known issues on RHEL

  • Install error when SELinux enabled – You may receive an error during installation of the Centrify DB2 package if you have SELinux enabled during installation. This may be avoided by one of the following two workarounds:

    • Temporarily disable SELinux. To disable SELinux, modify the /etc/selinux/config file as follows:


    • Change the file context on the appropriate library:

      chcon -t textrel_shlib_t /home/release/335_ESE_LNXAMD26_64_NLV/db2/linux26/install/
