6 <para>This option controls the maximum depth that winbindd
7 will traverse when flattening nested group memberships
8 of Windows domain groups. This is different from the

10 which implements the Windows NT4 model of local group
11 nesting. The "winbind expand groups"

15 <para>Be aware that a high value for this parameter can
16 result in system slowdown as the main parent winbindd daemon
17 must perform the group unrolling and will be unable to answer
18 incoming NSS or authentication requests during this time.</para>
20 <para>The default value was changed from 1 to 0 with Samba 4.2.
21 Some broken applications calculate the group memberships of
22 users by traversing groups, such applications will require
23 "winbind expand groups = 1". But the new default makes winbindd more reliable
24 as it doesn't require SAMR access to domain controllers of trusted domains.</para>
