PrincipalContext.ValidateCredentials Method

Definition

Namespace:

System.DirectoryServices.AccountManagement

Assembly:

System.DirectoryServices.AccountManagement.dll

Package:

System.DirectoryServices.AccountManagement v9.0.0

Creates the connection to the server and validates the specified credentials if the connection is successful.

Overloads

ValidateCredentials(String, String)	Creates the connections to the server and returns a Boolean value that specifies whether the specified username and password are valid.
ValidateCredentials(String, String, ContextOptions)	Creates the connections to the server and returns a Boolean value that specifies whether the specified user name and password are valid. This method performs fast credential validation of the username and password.

Remarks

The userName argument in both overloads of this method must take the form username (for example, mcampbell) rather than domain\username or username@domain.

ValidateCredentials(String, String)

Source:

Context.cs

Creates the connections to the server and returns a Boolean value that specifies whether the specified username and password are valid.

public:
 bool ValidateCredentials(System::String ^ userName, System::String ^ password);

public bool ValidateCredentials (string userName, string password);

member this.ValidateCredentials : string * string -> bool

Public Function ValidateCredentials (userName As String, password As String) As Boolean

Parameters

userName

String

The username that is validated on the server. See the Remarks section for more information on the format of userName.

password

String

The password that is validated on the server.

Returns

Boolean

true if the credentials are valid; otherwise false.

Remarks

The userName argument must take the form userName (for example, mcampbell) rather than domain\username or username@domain.
