I managed to get it to work, to an extent. It was looking for the
password for my exim user. I tried to seteuid at the point of the PAM
calls, but it fails. I want to be able to run exim as it's own user,
only taking root privileges as it needs - how to I get exim to become
root, seteuid as the user authenticating, then go back to it's 'regular'
user? I've got most of it coded to save the current euid/uid/egid/gid,
then switch back - but I can't switch because I'm not root. How does
exim regain root privileges when it needs them?
