Is there ~1000 value limit for multi-valued attributes is ADAM?Is there a 1000 (1024 of 1300) value limit to the number of values that can
assigned to a multi-valued attribute? Is this information available online/within any ADAM documentation? Thank you, - Jayesh Naithani Jayesh Naithani wrote:

There is no limit, but ADSI only handles 1000 values unless you use range limits. I have a sample VBScript program to enumerate group membership where the member attribute of the group object has are more than 1000 values. The program demonstrates how to use range limits. You probably can find other examples at the Microsoft site.

However,
you are right that Range Retrieval may be needed, so you are right to point that out as well. My understanding though is that ADAM's max range size is 1500, not 1000 like Win2K AD, so it should really not matter here. Thanks! Joe K.

multi-valued attributes. If you want unlimited values, you need to use a DN syntax (like 2.5.5.1) and make sure the attribute is linked with a proper linkID. Note that this must be done at creation time, so if your attribute is not like that already, you would need to start over with a different attribute. I'm not positive if or where this is documented, but I know it to be true. Joe K.

values being written. Once that limit is achieved you will see something like an admin limit exceeded error and you will no longer be able to add any new attribute values to the object unless the attribute in question has already had a value set. -- Show quoteHide quoteJoe Richards Microsoft MVP Windows Server Directory Services www.joeware.net ---O'Reilly Active Directory Third Edition now available--- http://www.joeware.net/win/ad3e.htm Joe Kaplan (MVP - ADSI) wrote: > I believe the limitation in ADAM is supposed to be 1300 for "normal" > multi-valued attributes. > > If you want unlimited values, you need to use a DN syntax (like 2.5.5.1) and > make sure the attribute is linked with a proper linkID.
