We're seeing an issue where su actions are not properly recorded when the user is in a screen session. What's interesting is that this appears to work properly on Ubuntu 12.04.2 running screen 4.00.03jw4 (FAU) 2-May-06 but does not work correctly on CentOS 6.04 running screen (FAU) 23-Oct-06. So maybe this is packaging related, but thought we'd start here.

When a user in a scree session runs "sudo su" the following appears in the Ubuntu logs:

In the CentOS log we get:

Notice that the second line does not indicate the name of the user which performed the sudo like we do in Ubuntu. Without this data, our logs are incomplete and log monitoring utilities do not properly fire.

Possible this is related to packaging or another part of the OS, possibly PAM?

Additional notes, includes showing that it does not work in tmux on either OS, are available here: https://gist.github.com/chrishas35/972fc8febad14bad1ae4.
