I'm using it because I need to tie auth to custom storage (actually
json-rpc requests to billing system).
Probably I can use lua but not sure and perlvdb concept is pretty
nice. Any other ideas how to do this?

yes, for now I just use examples provided
db_url is set like this:
modparam("auth_db", "db_url", "perlvdb:OpenSER::VDB::Adapter::Auth")

coredump? easy :)
you can pick core file itself here (it's pretty heavy to send to the list):

What do you mean by backtrace? log output or strace output?
