Password protection .htaccess method

[Rosyweb]

Hi, struggling with password protection on admin folder. I don't have the option of a control panel that will let me set the password protection on the admin folder, so am having to do this the .htaccess and . htpasswd style.

 

I posted a query yesterday but no replies, but maybe I phrased it badly - so here goes again.

 

What I'm really trying to get to work is the override in the .htaccess folder.

 

My code in this folder is:

 

AuthUserFile /.htpasswd

AuthName "Enter Password"

AuthType Basic

 

require valid-user

 

<Directory "/usr/local/apache/htdocs">

AllowOverride Limit

</Directory

 

I've getting the error message:

 

ERROR 500, Problem Running a Script...

 

 

I don't have access to change the server config files and my host is un-willing to change these, so should it be possible to over-write this from the .htaccess file alone? If so what am I doing wrong in my code to produce the error?
