Definition

Namespace:

System.ServiceModel.Security.Tokens

Assembly:

System.ServiceModel.Primitives.dll

Package:

System.ServiceModel.Primitives v8.0.0

Source:

SspiSecurityToken.cs

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.
