Not there still. In /var/www/html I created .htaccess:
# ls -lstra total 12 4 drwxr-xr-x. 4 root root 4096 Feb 6 16:06 .. 4 drwxr-xr-x. 2 root root 4096 Feb 17 13:32 . 4 -rw-r--r--. 1 root apache 21 Feb 17 13:32 .htaccess
# cat .htaccess Require all granted
restarted httpd, and still get the error.
[Fri Feb 17 13:36:17.366525 2017] [authz_core:error] [pid 5844] [client 192.168.160.12:48370] AH01630: client denied by server configuration: /usr/share/postfixadmin
That's not how the .htaccess file works. It needs to be in the directory specified in the postfixadmin.conf file - i.e. the configuration
<Directory "/usr/share/postfixadmin"> AllowOverride AuthConfig </Directory>
means to look in the .htaccess file in /usr/share/postfixadmin when accessing any file in that directory (and below) for authorisation information.
Putting it in /var/www/html will have no effect.
