API command authorize not recognized

[useronkel]

Using newest commit Every time when I try to acess the api, the only thing that would return is:

Notice: Undefined offset: 4 in /var/www/html/pwdb-lab.ecofis.de/api/index.php on line 46
{"error":"Access denied"}

Showing debug infos, it is clear that the index of var $uri is incorrect:

print_r($uri) ->
Array ( [0] => [1] => api [2] => index.php [3] => authorize )

Changing the variable in line 46 and 51 in /api/index.php from $uri[4] to $uri[3], authorization works

After authenticating a GET-Request to api/index.php/item/inFolders?folders=19 shows the following error:

Bad Request
Your browser sent a request that this server could not understand.
Size of a request header field exceeds server limit.

Setting LimitRequestFieldSize to 200000 in virtual host config solved the problem This should be part of the documentation as apache2 (in example) limits the header size to 8KB by default
