Yep, that's correct.

The reason it was originally done like that is because pdb_sql is
independent of any 3rd-party libraries. pdb_mysql can't be compiled
without the mysql library and pdb_pgsql can't be compiled without the
postgresql libraries. The Makefile.in I just sent you does indeed include
pdb_sql.c in the plugins rather then in the main Samba binaries. This
also means that there is no recompilation of Samba needed if you're
going to use the pdb_*sql plugins (althought you do need to have the
Samba source tree around for the header files).

I'm afraid not. All there is, is the header files in the Samba source.

This question is probably best answered by Volker or Jerry - I haven't
been watching the API changes closely lately.

Cheers,
