Ok. Not quite sure I'm following you. You mean pull user data from
PostgreSQL
and generate flat(db) user file for smtp-auth using
p5-Authen-SASL-2.10p0 ...
Aye, using whatever you fancy, probably loads of modules on CPAN that
will do most of what you want for your site. Perl is in base, so you
wont run the risk of a broken port of ruby/python/whatever stopping you
working after an upgrade.
Same for /etc/postfix/{aliases,canonical.map,virtual.map}
...
Then pull out 'other' Postfix data maps via (f.ex) Perl script across
my 'mail farm'.
Not sure yet how to do it - but I figure it out.
PostgreSQL is brilliant as you can have views of multiple tables, such
as user id passwd, then reference another accounts table with foriegn
keys to see if payment is upto date, how much they paid (disk quota).
Then from this one view, just select * and dump that data into flat
files, then push to your front line smtp, imap, webmail, shell... boxes.
No fancy SQL in the scripts, let the DB do the work for you with views
stored procedures. (Your business logic is separate from the oily bits
of service implementation)
Implement another service, such as web hosting accounts, then just write
another SQL view, and another Perl script to config apache, etc, etc.
My basic point is this: you can go to a lot of bother to get some
services to auth against SQL, then you want to bring up another service
and there is no way of using SQL directly, so you write some scripts to
generate flat files. Then you bring up another service, So why not
just do it that way from the beginning? After all, the app was developed
to use flat files, so as a mere user of an app, why fight against the
developer?
How about - using OpenLDAP?
Same thing. Flat files are fast and reliable, and are basically the only
way to give users shell access (mutt/pine) on OpenBSD as login wont auth
against LDAP or SQL.
