ReferralChasingOption Enumeration

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

Namespace:  System.DirectoryServices
Assembly:  System.DirectoryServices (in System.DirectoryServices.dll)

public enum ReferralChasingOption

Member nameDescription
NoneNever chase the referred-to server. Setting this option prevents a client from contacting other servers in a referral process.
SubordinateChase 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.
ExternalChase external referrals. If no referral chasing option is specified for a directory search, the type of referral chasing performed is External.
AllChase referrals of either the subordinate or external type.

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.
