adagios 1.6 broke after upgrading to apache2.6

[arthur sherman]

i get 

Bad Request (400) on request to any adagios page.

nagios 4.1 w/ still works fine.

looks like an authorization issue but i didn't locate the files which need to be modified w/ the new apache auth params.

apache2.conf looks ok, using the new params.

increased apache logging level and got the following in error.log for each request for an adagios page:
