[Box Backup] Certificate for Windows

[ken]

I am trying to create certificates for Windows clients and sign them with
boxbackups CA.

Here is what I do:

Create an account:
/usr/bin/bbstoreaccounts create 1234 0 4096M 4505M

Generating private key:
openssl genrsa -out /etc/box/bbackupd/1234-key.pem 2048

Generate certificate request (is there a boxbackup config file I should
use?):
openssl req -new -key /etc/box/bbackupd/1234-key.pem -sha1 -out
/etc/box/bbackupd/1234-csr.pem

Generate keys for file backup:
openssl rand -out /etc/box/bbackupd/1234-FileEncKeys.raw 1024

Sign certs:
cd /etc/box
/usr/bin/bbstored-certs ca sign bbackupd/1234-csr.pem

And get this error:
No subject found in CSR bbackupd/1234-csr.pem at /usr/bin/bbstored-certs
line 336.

Thanks in advance!

Cheers!
