I'm using LDAP to get users from Active Directory domain controller, and I want to resolve MaxPageSize
allowed to use it later.
There is a difficult AD-specific mechanism to get actual MaxPageSize
policy value for specific domain controller.
Is there is any mechanism to get MaxPageSize
policy for current established LDAP connection, except guessing? I expect to get some kind of virtual object like RootDSE
from DC or something.
There is no need to know current value of MaxPageSize
for DC when using paged requests.
Passing PageResultRequestControl
(1.2.840.113556.1.4.319
) with value greater than DC's MaxPageSize
value makes DC answer with pages of MaxPageSize
records per page without any errors.
For Active Directory LDAP on Windows Server 2008 and newer, hardcoded limit is 20000
, so I can pass 20000
in request and I will get responses of maximum MaxPageSize
entries in response.
