Be aware that ZEN does not store all it's information in eDirectory.
However, all info that ZEN stores in eDirectory could however be set/
modified by DSImport.
Not being an expert for ZEN, I could not be of much help for how the
req'ed attributes need to look like, but you may use other tools like
iManager or LDAP tools to test and identify the necessary syntax, then
use DSImport for automation.
Use DSReport or LDAP tools to check, how the attribute values _should_
look like, and what Aux Classes are set for properly working objects.
To be more specific, I'd need more details on what exactly you
changed, samples, error codes, etc.
Good luck
