Bolke de Bruin updated RANGER-827:
----------------------------------
Attachment: usersync.patch
This patch add support for using "getent" and is implemented equivalent to the
NFS mapping support in hadoop and removes the less than ideal reliance on
"/etc/passwd" and "/etc/group"
it adds "ranger.usersync.unix.update_millis_min" which defaults to 1 minute.
Next to that it ass support for adding "missing" users that are available in
"getent groups", but do not get returned in "getent passwd" due to performance
restrictions. This is activated by setting
ranger.usersync.group.idmapenabled to True
> Use system supplied mechanism to get users and groups on unix

> 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 is is required to add
> these using the group information.
