Do multivalued attributes in ADAM have a limit to the number of values that they can hold?
ADAM (as with Active Directory running at Windows Server 2003 forest functional level) places no limits on the number of linked attribute values that a multivalued attribute can hold. For nonlinked values, it is recommended that a multivalued attribute contain no more than 1,500 values. For information about linked attributes, see “Linked Attributes” on the Microsoft MSDN Web site. For information about member as an example of a multivalued attribute in Active Directory, see “Enumerating Groups That Contain Many Members” on the Microsoft MSDN Web site.
