Unable to access to S3 with temporary credentials.

[aghiles]

I am not certain it's the best place to report this but ...

I am using libs3 and I am trying to access a bucket from outside AWS. If I used the "root" <key,secret> pair everything is fine.

Now, if I generate temporary <key,secret,token> credentials (using sts:AssumeRole) I can't access the bucket (error is ErrorInvalidAccessKeyId). Access is possible only from inside AWS.

Is this a bug in libs3 or is it my doing something wrong?

Thank you!
