Change password support (Linux)
Db2® database products provide support for changing passwords on Linux® operating systems.
This support is implemented through the use of security plug-in libraries called IBMOSchgpwdclient.so and IBMOSchgpwdserver.so.
To enable password change support on Linux, set the database manager configuration parameter clnt_pw_plugin to IBMOSchgpwdclient and srvcon_pw_plugin to IBMOSchgpwdserver.
You must also create a PAM configuration file called "db2" in the /etc/pam.d directory.
