The ReferralChasingOption enumeration specifies if and how referral chasing is pursued.

public enum class ReferralChasingOption
public enum ReferralChasingOption
type ReferralChasingOption = 
Public Enum ReferralChasingOption


All 96

Chase referrals of either the subordinate or external type.

External 64

Chase external referrals. If no referral chasing option is specified for a directory search, the type of referral chasing performed is External.

None 0

Never chase the referred-to server. Setting this option prevents a client from contacting other servers in a referral process.

Subordinate 32

Chase only subordinate referrals that are a subordinate naming context in a directory tree. The ADSI LDAP provider always turns off this flag for paged searches.


When a server determines that other servers hold relevant information the server might refer the client to another server to obtain the result. Referral chasing is the process by which a client contacts the referenced server to continue the directory search.

Use the constants of this enumeration to set up search preferences for referral chasing. The action involves assigning the appropriate fields of DirectorySearcher to elements of the ReferralChasingOption enumeration.

The ADSI LDAP provider supports external referrals for paged searches, but does not support subordinate referrals during paging.
