Michael Walker commented on TEIID-1659:
---------------------------------------

I did follow up on this question from Marc and again from Ken, but maybe it did not make it’s way back to Steve. Here was my response:

> The custom connector written for <customer> does not support paging. 
> It's something <customer> chose not to implement back in 2007 because 
> the version of Sun's directory server used did not 
> support it, either. There were some placeholders made in the code 
> marking where it could be implemented for AD in the future. This is 
> something that could be implemented by <customer> or by RH professional services.
>
> As a workaround, they should increase the maxPageSize value in AD. 
> LDAP admins are usually opposed to doing this across the board; 
> perhaps this can be done just for a specific user, or only for the 
> particular subtree they're having issue with, to limit the impact of this change.

> I'm pretty sure this won't work, but one thing they might try out is 
> to set the "maxBatchSize" property of the LDAP connector to the value 
> of the maxPageSize property in AD (typically 1000). Since it's so easy 
> to test, it's worth a try but I don't think it will make a difference.

I think the follow-up was that the 5.5.4 connector did not support it, either. So, it would have to be implemented.

> Active Directory has a setting MaxPageSize that limits the number of records of query results returned in a batch.  The EDS LDAP connector/translator should support this setting so it can page through the results and retrieve all results.  Not just up to MaxPageSize.  Ideally this would be a configurable parameter that the user must set to match the MaxPageSize value on the AD server.  For more info: http://support.microsoft.com/kb/315071.
