Summary0007461: Groups and plugins not properly enumerated
DescriptionThe AD Connector uses getent to enumerate group memberships, but this is no longer working. A change in the Samba 4.2 defaults was the root cause:

winbind expand groups (G)

           This option controls the maximum depth that winbindd will traverse
           when flattening nested group memberships of Windows domain groups.
           This is different from the winbind nested groups option which
           implements the Windows NT4 model of local group nesting. The
           "winbind expand groups" parameter specifically applies to the
           membership of domain groups.

           Be aware that a high value for this parameter can result in system
           slowdown as the main parent winbindd daemon must perform the group
           unrolling and will be unable to answer incoming NSS or
           authentication requests during this time.

           The default value was changed from 1 to 0 with Samba 4.2. Some
           broken applications calculate the group memberships of users by
           traversing groups, such applications will require "winbind expand
           groups = 1". But the new default makes winbindd more reliable as it
           doesn't require SAMR access to domain controllers of trusted
           domains.

           Default: winbind expand groups = 0
