Questions

• Should we have a configuraton sub tree with sane default values?
• Should we store the current values in the LDAP (CPU, RAM, ...)?
• Will we store the network configuraton in the LDAP?
  • If yes, how will we store the additional networks in the LDAP (shared network)?
• How will we make sure, not to bill the IPv4 netwoks, belonging to a reseller and/or customer?
  • For example Fence IT AG?
• Will we have both sstBelongsToDomainID and sstBelongsToDomainUID or just one or the other?
