[Samba] LDAP group objects?

[Daniel Turner]

I'm not seeing my LDAP groups listed when I use Windows file sharing tools
to modify ACLs on a share.

I see all of the LDAP users.

Ubuntu 16.04, hosted LDAP ("in the cloud", although I hate that term,
provided by JumpCloud.com), no AD.

I'm able to assign LDAP users to ACLs.

The groups are of objectClass 'groupsOfNames'.

Is this expected behavior?
