3.1.1.3.2.31 msDS-TopQuotaUsage

Returns a multivalued set of strings specifying the top 10 quota users in all NC-replicas on this DC. The format of each value is as follows, where quota usage is measured in number of objects:

<MS_DS_TOP_QUOTA_USAGE>

<partitionDN> DN of NC-replica </partitionDN>

<ownerSID> Security Identifier (SID) of quota user </ownerSID>

<quotaUsed> Amount of quota used by this quota user </quotaUsed>

<tombstoneCount> Number of tombstoned objects owned by this quota user </tombstoneCount>

<liveCount> Number of live (non-deleted) objects owned by this quota user </liveCount >

</MS_DS_TOP_QUOTA_USAGE>

A client qualifies the attribute description for this attribute in an LDAP query with a "range qualifier" to specify a different range of quota users to return other than the top 10. The DC responds to this by returning the quota usage for the requested range of quota users. Following are examples of range qualifiers and what would be returned:

  • An attribute specification of the form msDS-TopQuotaUsage;Range=0-* will return the complete list of quota usage.

  • An attribute specification of the form msDS-TopQuotaUsage;Range=1-9 will return the second highest through the 10th highest quota usage.

  • An attribute specification of the form msDS-TopQuotaUsage;Range=2-2 will return the third highest quota usage.

The caller must have the RIGHT_DS_READ_PROPERTY access right on the Quotas container (see section 6.1.1.4.3). If the caller does not have this access right, the search operation will succeed but no results will be returned.
