7 <para>This option controls the maximum depth that winbindd
8 will traverse when flattening nested group memberships
9 of Windows domain groups. This is different from the
10 <smbconfoption name="winbind nested groups"/> option
11 which implements the Windows NT4 model of local group
12 nesting. The "winbind expand groups"
13 parameter specifically applies to the membership of
16 <para>Be aware that a high value for this parameter can
17 result in system slowdown as the main parent winbindd daemon
18 must perform the group unrolling and will be unable to answer
19 incoming NSS or authentication requests during this time.</para>
21 <para>The default value was changed from 1 to 0 with Samba 4.2.
22 Some broken applications calculate the group memberships of
23 users by traversing groups, such applications will require
24 "winbind expand groups = 1". But the new default makes winbindd more reliable
25 as it doesn't require SAMR access to domain controllers of trusted domains.</para>
