PAM authentication for Erlang applications ========================================== This library used to be part of ejabberd which still uses it if configured to do so. Because it is now packaged as a separate library, the location of the epam binary has changed. If you have used dpkg-statoverride before, you will need to do the same for the new binary location now. As an example, to make epam setgid shadow, you can use: dpkg-statoverride --add root shadow 02755 /usr/lib/erlang/p1_pam/bin/epam and to make epam setuid root you can do: dpkg-statoverride --add root ejabberd 04754 /usr/lib/erlang/p1_pam/bin/epam Note that we set o-x there so that only users in the ejabberd group are able to elevate their privileges by executing this program. Please see ejabberd's README.Debian for further information and also have a look at the Debian Policy chapter 10.9 - "Permissions and owners".
