Creating users in Active Directory through LDAP connector

Hello,

If we need to create users in Active directory using LDAP connector, what are the options for the following:

1) Update back into SAP from AD. LDAP connector updates only in one direction i.e from SAP to Active directory.

2) Can we add additional fields in LDAPMAP which are not standard e.g can we we write our own code to extract data from HR to map the value with an attritube within Active directory?

Regards,

Ahmad
