 I ran it as a wrong user, and I expect b10-auth to report the permission
 denied error and quit, so far so good, but when it is cleaning up it
 segfaults:

 {{{

 }}}

 Looks like either the remote config data needs a cleaner initialization or
 that main.cc call needs to check first whether is succeeded setting up in
 the first place
