Ah, right you are, thanks!

Missed that (it was staring me in the face) - doveconf -n shows:

userdb {
   driver = passwd
}
userdb {
   args = /etc/dovecot/dovecot-sql.conf.ext
   driver = sql
}

One thing about dovecots config I've learned during this process... it 
is confusing sometimes to determine where any given setting is coming 
from, given the number of different default config files..

Grepping of course will help you find it, but it would be nice if there 
was some way to simplify this...

Maybe cut down on the number of different config files (ie, combine all 
of the different auth-* files into one)?

Or maybe a verbose flag you could pass to doveconf -n - ie, 'doveconf 
-nv' - that would sort the output based on the config file that each 
group of settings came from, with a comment above each group of 
settings, ie:

doveconf -nv
...
# from /etc/dovecot/conf.d/auth-system.conf.ext
userdb {
   driver = passwd
}
# from /etc/dovecot/conf.d/auth-sql.conf.ext
userdb {
   args = /etc/dovecot/dovecot-sql.conf.ext
   driver = sql
}

But, like I said, it isn't all that difficult to find them so not a huge 
deal.

Anyway, problem solved - thanks again Tom...
