Hm, I was more relaxed in my original RFE and allowed records like:

dn: cn=Test User,cn=staged users,cn=accounts,cn=provisioning,dc=example,dc=com
objectClass: top
objectClass: organizationalperson
cn: Test User
sn: User
nsAccountLock: True

RDN is just part of the problem though - note that the user-unstage command
would also need to generate the default attributes for the user (including
kerberos principal ones) - and we need to somehow authorize that LDAP modify
operation.
