dovecot - Nov 2017 - Passing information from passdb to userdb

I'm trying to hack together a new authentication back-end and I wanted to
know if it's possible to pass values from passdb to userdb in the
auth_request structure at authentication time. I modified struct auth_request in
auth-request.h to contain a new variable and it gets set properly in my passdb,
however the value is not there when checking for it userdb.
I'm very novice when it comes to Dovecot programming so any help is
appreciated.
Thanks!

The best way to is to use auth_request_set_userdb_field(request, key,
value);

and it will be available in userdb.

Thanks. If I do that in my passdb-test.c file, it core dumps. I did something
simple like:
auth_request_set_userdb_field(auth_request, "customFlag",
dec2str(50));
However, auth_request_set_field() used like this:
auth_request_set_field(auth_request, "customFlag", dec2str(50), NULL);
doesn't core dump.
What's the difference between both functions and finally, how do I retrieve
values from auth_request ?

Thank you

I found a working solution, replying here to confirm it's the proper way of
doing it and in case others might need the same
setting the value in passdb:
auth_request_set_field(request, "authlocation", dec2str(9),NULL);
reading the value in userdb:
auth_fields_find(auth_request->extra_fields, "authlocation")
