page size. Because of variable overhead requirements and the variable number of
attributes that an object might have, it is impossible to provide a precise
limit for the maximum number of multivalues that an object can store in its
attributes. For all practical purposes, the size of objects is not significant
in Windows Server 2003 Active Directory and is not significant

estimates into account and generalizing about the other values that the object
might store, the practical limit for number of multivalues stored by an object
is estimated at 800 nonlinked values per object across all attributes.<o:p></o:p></span></p>

"NoteThe list of devices associated with a user is stored in the directory
as a multi-valued attribute. If you are using the embedded Cisco Unified
CallManager 4.x directory (known as DC Directory), the maximum number of
devices that can be associated with a user is 2,000 (or 2,500 if all
subscribers in the cluster are dual-CPU servers). However, Microsoft Active
Directory limits the number of values that can be stored in a multi-valued
attribute. The total size of the record should never exceed 7,000 bytes,
which allows for approximately 850 attribute value"<br>

Usually this is limited by the field size in the associated ldap storage base.<br>
