Description

The unix user sync currently reads /etc/passwd /etc/groups . This is often not a reflection of users and groups available on a system especially when nsswitch is configured (eg. sssd, ldap etc).

Secondly in some cases groups will contain user names that are not returned with "getent passwd", especially "external users" and it is required to add these using the group information.
