问题 I'm validating users in an Active Directory store as follows: // using System.DirectoryServices.AccountManagement; // located in System.DirectoryServices.AccountManagement.dll using (var context = new PrincipalContext(ContextType.Domain, server, container, ContextOptions.Negotiate, validateUsername, validatePassword)) { var valid = context.ValidateCredentials(validateUsername, validatePassword); if (valid) { Console.WriteLine("SUCCESS!"); using (var userContext = UserPrincipal.FindByIdentity

问题 I have a requirement to check if the users in my application are active users in active directory. I need to send a notification when one of the user alias becomes invalid. In most of the examples I see validating only one user at a time against ADFS using LDAP which is going to take a very long time large number of users. Is there any way by which I can validate by sending a list of users and validate, so that it will be faster? Thanks. 回答1: Out the box in ADFS, no. This sounds like

问题 Searcher.Filter = "(&(objectCategory=person)(objectClass=user)(!givenName=""))" I'am using the above active directory search filter to try and get users whose FirstName in active directory is not empty or NULL but the filter still returns null entries. What should I change in the filter to only retreive users with a first name that is not NULL or Empty 回答1: Can you try : Searcher.Filter = "(&(objectCategory=user)(objectClass=user)(givenName=*))" To build a filter you can use registered query

问题 Could you help me and tell if im using the "using statement" correctly in my directoryservice function that gets distingushed name from my Active Directory. I want to dispose and close objects correctly. Code: Public Function GetObjectDistinguishedName(ByVal objClass As objectClass, _ ByVal returnValue As returnType, _ ByVal objName As String, ByVal LdapDomain As String, _ Optional ByVal includeLdapPrefix As Boolean = True) As String Dim distinguishedName As String = String.Empty Dim
