failing to make created user's Admin

[krispayne]

I've noticed lately that my users are failing to be made as admin.

I'm creating the packages on El Cap, deploying with Casper Imaging.

I recently changed the UID's to be above 500 (file vault stuff), other than that I'm not sure what the issue is.

It may be possible that it's not as compatible with El Capitan as I thought?

This is possibly related to Casper, and not an issue with createuserpkg.
