I'm trying to import certificates in bulk with the following command:
bin/ejbca.sh ca importcertdir <username-source> <caname> <status> <certificate dir=""> <endentityprofile> <certificateprofile>

At a certain point, after some successful import, i obtain this error:
Error: Wrong number of ORGANIZATIONUNIT fields in Subject DN.

What's the cause?How can i solve it?
