The problem seems to be solved, but the solution does not seem valid.
There appears to have been a conflict between these two groups of
directives:
ScriptAlias /adminjr-cgi/
"/Users/leegoddard/src/www/northfoto2/adminjr-cgi/"
<Directory "/Users/leegoddard/src/www/northfoto2/adminjr-cgi/">
... Require group admin ...
</Directory>
Conflicted with:
<LocationMatch "/admin/*">
At least, when I changed the latter to the below, all behaved as expected:
<LocationMatch "/admin/index.shtml">
... Require group adminjr ...
</Location>
Have I misunderstood the PCRE engine, or is this a bug...?
Thanks
Lee

> <LocationMatch "/admin/*">
This matches a URL with /admin anywhere inside of it, followed by 0 or
more slashes. So it matches and overrides your <Directory> block.
No regex or wildcard is required for what you probably intended
(Location /admin/), but if you use a regex and intend it to match
things that "start with" the arg, you have to anchor with ^. You also
need to get the wildcard right (* modifies what comes before it, e.g.
.*)

No, don't look it up, I'll have a poke around. I have done a fair amount
of reading recently, but this commandment did not stick in my mind. I
realise it would be foolish to mix Directory and Location on the same
resource, but the URIs resulting from those directives bore no relation
to each other, there is no way that /admin-cgi/ can map to /admin/*

I agree that the LocationMatch in question was ugly and silly, and I
would not put it into production, but it should have worked, I think. At
least, I await reason as to why it ought not to.
Thanks for your help

Thou shalt not mix <Directory> and <Location>!
(the gory details are explained somewhere in the docs; I'm not
about to look it up).
Oh, and you clearly don't want PCRE or any *Match directive.
