When attempting to pull a list of objects from a bucket with a capital letter the following error response is thrown:

"SignatureDoesNotMatchThe request signature we calculated does not match the signature you provided. Check your key and signing method."

Example code to reproduce:

$s3 = new Zend_Service_Amazon_S3($key, $secret_key); $buckets = $s3->getBuckets(); foreach ($buckets as $bucket) { $list = $s3->getObjectsByBucket($bucket); }

In this case, if the bucket name has a capital letter (ie 'Capital') then the list will return false. Amazon does support buckets with capital letters even though the Zend Framework documentation says it does not.
