IDMU=Identity Management for Unix has been deprecated from AD, the last AD version to support it is 2012, but the RFC 2307(unix) attributes still exist in AD, we just need to edit them manually in ADUC=Active Directory Users and Computers manually for each user, via Advanced Options. See the link below :
These are the attributes to edit:
| Field on IMU Unix Attributes tab | RFC2307 AD attribute |
|---|---|
| UID | uidNumber |
| Logon Shell | loginShell |
| Home Directory | unixHomeDirectory |
| Primary group name or group identifier (GID) | primaryGroupID |
