user-enrollment package signing issues

Contributor III

So I'm trying to sign our user-enrolled package and having some issues. For info sake, here's what I've done:

1) Created a request certificate.
2) Went to my developer account on Apple and created a Developer ID.
3) Downloaded Developer ID and installed into my keychain
4) Selected the developer ID and my private key and exported to a p12 file
5) Went into user enrollment page, and tried to upload p12 file but keeps getting Password Invalid error. I did this like 5 times exporting it with a different password and it didn't like any of them.

Were currently running Casper 9.8.

Anyone else similar issues? Any solution?
