Apache AuthType not set 500 Error

Question

It s been a while since I used the Apache httpd web server   I m firing up a local server for a project and when I try to request localhost index html  I get a 500 error and I see this in the error log    Tue Jan 21 09 23 58 2014   crit   client   1  configuration error   couldn t perform authentication  AuthType not set    index html  Tue Jan 21 09 23 58 2014   error  an unknown filter was not added  DEFLATE  Tue Jan 21 09 23 58 2014   crit   client   1  configuration error   couldn t perform authentication  AuthType not set    favicon ico   It looks like there are possibly 2 errors here in the apache config  one related to  AuthType not set   and possibly another related to  filter was not added  DEFLATE    I dont know what these means or where to start digging in     A basic Google search revealed this link which indicates that the culprit may be  Require all granted    This line in my httpd conf may be involved    lt Directory   var www  gt      AllowOverride None       Allow open access      Require all granted  lt  Directory gt    This apache config is mostly what is used in production for this project  so I know this works  just not currently on my workstation   What does this mean and what should I try next   I did try commenting out  Require all granted  and restarting apache but to no avail   Following this SO question I also loaded mod authz host  LoadModule authz host module modules mod authz host so   and added  Allow from all   restarted the server   but the issue persists   The deflate issue appears to be unrelated  and was easily solved by adding   LoadModule deflate module modules mod deflate so   The question remains  how do I solve this 500 error    Tue Jan 21 09 44 20 2014   crit   client   1   configuration error   couldn t perform authentication   AuthType not set    index html

Alternatively  this solution works with both Apache2 version  lt  2 4 as well as    2 4  Make sure that the  version  module is enabled   a2enmod version   And then use this code instead    lt IfVersion  lt  2 4 gt      Allow from all  lt  IfVersion gt   lt IfVersion  gt   2 4 gt      Require all granted  lt  IfVersion gt

I think that you have a version 2 4 x of Apache   Have you sure that you load this 2 modules    - mod authn core  - mod authz core  LoadModule authn core module modules mod authn core so LoadModule authz core module modules mod authz core so   PS   My recommendation for authorization and rights is  by default     LoadModule authn file module modules mod authn file so LoadModule authn core module modules mod authn core so LoadModule authz host module modules mod authz host so LoadModule authz groupfile module modules mod authz groupfile so LoadModule authz user module modules mod authz user so LoadModule authz core module modules mod authz core so LoadModule auth basic module modules mod auth basic so LoadModule auth digest module modules mod auth digest so

The problem here can be formulated another way  how do I make a config that works both in apache 2 2 and 2 4   Require all granted is only in 2 4  but Allow all     stops working in 2 4  and we want to be able to rollout a config that works in both   The only solution I found  which I am not sure is the proper one  is to use     backwards compatibility with apache 2 2 Order allow deny Allow from all    forward compatibility with apache 2 4 Require all granted Satisfy Any   This should resolve your problem  or at least did for me  Now the problem will probably be much harder to solve if you have more complex access rules     See also this fairly similar question  The Debian wiki also has useful instructions for supporting both 2 2 and 2 4

You can try sudo a2enmod rewrite if you use it in your config

Just remove comment the following line from your httpd conf file  etc httpd conf   Require all granted  This is needed till Apache Version 2 2 and is not required from thereon

Remove the line that says  Require all granted   it s only needed on Apache   2 4
