Gets a value that indicates whether to allow NTLM authentication.

public:
 property bool AllowNtlm { bool get(); };
public bool AllowNtlm { get; }
member this.AllowNtlm : bool
Public ReadOnly Property AllowNtlm As Boolean

Property Value

Boolean

true if NTLM authentication is allowed; otherwise, false.

Remarks

Setting this property to true allows authentication to downgrade to NTLM if Kerberos is not available.

Setting this property to false causes Windows Communication Foundation (WCF) to make a best-effort to throw an exception if NTLM is used. Note that setting this property to false may not prevent NTLM credentials from being sent over the wire.
