I don't know if there's a nice solution. If your users are locally
stored in /etc/passwd you can grab the uid via stat and then look them
up from /etc/passwd using a ${readfile} and some regex's. The horrifying
solution:
Figure out the owner of the "/etc/passwd" file and the "/etc/openvpn"
dir:
[EMAIL PROTECTED]:~$ ls -l /etc/passwd
-rw-r--r-- 1 root root 1858 2007-05-25 07:34 /etc/passwd
[EMAIL PROTECTED]:~$ ls -ld /etc/openvpn
drwx------ 5 openvpn openvpn 4096 2007-05-02 20:52 /etc/openvpn
[EMAIL PROTECTED]:~$
[EMAIL PROTECTED]:~$ /usr/sbin/exim -be
