A lot of stuff :-) 140-odd lines and then it includes farmrecipes.php 
with another 50-odd lines. The field's local/config.php is only a few 
lines, though.

Ah! That'll be it then. The first lines of farmrecipes.php are:

$Author = $AuthId;

Thinks: If authuser.php is the problem, I'm happy to add a field 
specific include prior to calling it.

Okay. I'm not doing anything tricky, the vast majority of it is setting 
variables for passwords, searches, uploads, notify and a few markup 
overrides. Then there are the recipes.

I'm happy to email the files to you, if it helps.

I dug out a few messages from the archives that indicated that this 
wasn't an easy issue.

If it makes it easier, I can live with only changing $DefaultGroup. 
Though, I suspect this doesn't change things.

If the worst comes to the worst, I can use an Apache rewrite, I suspect.
