Create SubCA failed.

I am getting this error when I try to create a SubCA in Yast CA module.

RuntimeException:-1:Issuing the certificate failed.

Anyone know how to fix this?

I found this after having the same problem and noticed no one has responded so this is for the next guy that has this issue.

Simply lower the valid days to one day below the valid days of the Master CA and the certificate will generate no problem.
