[Mono-list] ASP.Net Problem in 2.8.1

[Abe Gillespie]

I'm getting this now:

No access to the given key

Description: HTTP 500. Error processing request.

Stack Trace:

If I run a command-line xsp session as root it works fine.  I saw that
it needed access to /usr/local/mono/2.8.1/etc/mono/registry where it
created and updates a file named last-btime.  I did "chmod o+w -R" on
the registry dir but that didn't seem to help.  Now my public site
runs fine but the site behind a login is what breaks; I'm pretty sure
it's something going on with the .Net Recaptcha control I'm using.

Can I fix this by setting up a registry for the apache user?  If so, how?

Thanks.
