Hi,

here is was I get when I fetcht he ACL:

<?xml version="1.0" encoding="UTF-8"?>

As a test, I'm trying to set the exact same ACL on the same object.

Why AccessDenied when admin has FULL_CONTROL ?

[JMLX42]

Forgot to mention admin also has FULL_CONTROL on the bucket:

Here are the logs:

Hi,

How about using s3curl.pl --put <filename> --contentType application/xml ? A complete command could be:

./s3curl.pl --id=admin --put <your xml file path> --contentType application/xml -- -s -v -x localhost:8010 http://s3.amazonaws.com/4efbf4ac1c9fdf6a/J34/J34Lot/J34Lot2xx/J34Lot227.vue.scene

IIRC, s3curl.pl requires to use --put|--delete|--post and --contentType options explicitly to calculate them as a correct signature of AWS Authentication Version 2 when using such http methods except GET.

Command samples are here.

About --contentType:

$ curl --contentType
curl: option --contentType: is unknown

How about using s3curl.pl --put --contentType application/xml ? A complete command could be:

So you mean put my ACL in a temporary file instead of a shell variable passed via stdin ?

Yes, I mean so. Perhaps, you could use --put - to read contents from stdio such as echo $ACL | ./s3curl.pl --put - --contentType application/xml -- <curl options> since s3curl.pl passes filename as a param of -T option of curl...

[JMLX42]

--contentType application/xml

Again, using --contentType throws the following error:

curl: option --contentType: is unknown
