WSGIDaemonProcess is configured in /etc/httpd/conf.d/ipsilon-idp.conf. If you need to debug the lasso C code by running ipsilon under gdb you need to attach to the wsgi process. Currently the only reliable way to determine the wsgi pid is to look for wsgi process pid in /var/log/httpd/error_log, e.g.:

mod_wsgi (pid=12345): Starting process 'idp' with uid=499, gid=499 and threads=15.

If one tries to determined the wsgi pid as a child of httpd by using ps it's ambiguous as to which child process is the ipsilon wsgi pid. However if one adds

display-name=idp to WSGIDaemonProcess then when you run ps you'll see idp as a process name, making it much easier to attach gdb.
