An issue was found while storing blobs in a mongo database. JClouds was used for this.
Jcloud seeks the "Everyone" principal when using Windows, but the currently used version simply checks for that exact string. Which causes malfunction when using other Windows languages ("Iedereen" is received in Dutch)
This has been resolved in a more recent version of Jclouds. See: https://github.com/apache/jclouds/blob/5ac92111c4e9347c492a16ecd402acafdb1f9cd7/apis/filesystem/src/main/java/org/jclouds/filesystem/util/Utils.java#L115
This issue should be resolved by updating the Jclouds version.
