The limit is 1000 on 2K and 1500 on K3/ADAM. These values can be tweaked. The general purpose reason is to conserve resources on the LDAP server. Consider result sets have to be pulled into memory to be encoded to send back to clients. If you have lots and lots of simultaneous queries with huge resultsets you could quickly cause harm to an LDAP server as it runs low on resources.
As to why MS did it and others didn't. Possibly the others are not thinking properly about large scale or heavily loaded implementations. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Thursday, September 22, 2005 12:31 PM To: [email protected] Subject: [ActiveDir] LDAP search limitations Apologies for asking this question, since it's been posed before (?), but can anyone offer me a brief description of why AD only returns (by default) 1024 entries when an LDAP search is performed? Is it a question of performance? Why is the searcher not offered all records that meet the search criteria? Questions have arisen as to why MS implemented a limit since (apparently), other LDAP implementations do not enforce these limits. thanks, neil --------------------------------------- Neil Ruston Nomura International Plc Tel: 020 7521 3481 [EMAIL PROTECTED] PLEASE READ: The information contained in this email is confidential and intended for the named recipient(s) only.
