Bug in autolog - User name with more then 8 characters

Autolog is a tool that helps the management of user sessions, the idea is to control the time that users are allowed to use the computer, and check for idle users.

The code that i'm working on has a bug that users with more then 8 characters (like leonardol, for instance) cannot be logged out due to the use of ps command. The ps command shows the userid instead of the user name if that user name has more than 8 chars.

So, this patch can fix the autolog.c code, if you need the files used to build this patch, send me an email.

I could not find the original developers of this tool, and the debian package has been abandoned also.
