Auth Problems with phpMyAdmin / Apache Proxy

[Dayo]

Finally got it working.

Changed my setup such that Apache only listened on internal IP 127.0.0.1
and moved the auth process to Nginx.

I think (but didn't verify) the behaviour I saw may have been because my
htpasswd file had been created using only the -c flag and not -c -d.
