Problems connecting to my Magento OAuth1 [closed]

Question

I am trying to connect my web application to my Magento OAuth1. The problem is when I try the URL //mydomain/store/oauth/initiate I get a page that says: "This webpage is not found" (Error code: ERR_FILE_NOT_FOUND).

Here is my Apache .htaccess configuration (part of it):

############################################
## enable rewrites

    Options +FollowSymLinks
    RewriteEngine on

############################################
## you can put here your magento root folder
## path relative to web root

    RewriteBase /store/

############################################
## uncomment next line to enable light API calls processing

#    RewriteRule ^api/([a-z][0-9a-z_]+)/?$ api.php?type=$1 [QSA,L]

############################################
## rewrite API2 calls to api.php (by now it is REST only)

    RewriteRule ^api/rest api.php?type=rest [QSA,L]

So what am I doing wrong?
