Subject: [PATCH 3/3] Make sure default buffer for nsswitch operations is big
|
|
|
94cced |
enough
|
|
|

|
|
|
94cced |
By default initial buffer sizes for getgrent/getgrnam/... functions
|
|
|
94cced |
are way small for large groups in Active Directory so make sure
|
|
|
94cced |
we have something reasonable for groups with hundreds or thousands members.
