[DOC BUG] SSO prevents API access

[andreas-p]

After I enabled SSO on an I-Doit installation, the API access via X-RPC-Auth-Username and X-RPC-Auth-Password won't work any more, because Apache will redirect to the OIDP via 302 status.

I suggest to extend the Apache Configuration Section to include the following lines:

    <Location />
        AuthType openid-connect
        Require valid-user
        AllowOverride All
    </Location>

    <Location /src/jsonrpc.php>
        AuthType none
        AllowOverride None
        Require all granted
    </Location>

Which will except the API from hitting the OAuth configuration.
