c# - 具有使用 SSL 的上下文的 UserPrincipal

Question

我有一个使用 SSL 的 PrincipalContext。这在使用 Context.ValidateCredentials() 之类的方法时效果很好。但是，当我需要使用 UserPrincipal.FindByIdentity() 查找用户时，出现以下错误:

System.Runtime.InteropServices.COMException: The server is unwilling to process the request. at System.DirectoryServices.DirectoryEntry.Bind(Boolean throwIfFail) at System.DirectoryServices.DirectoryEntry.Bind() at System.DirectoryServices.DirectoryEntry.get_SchemaEntry() at System.DirectoryServices.AccountManagement.ADStoreCtx.IsContainer(DirectoryEntry de) at System.DirectoryServices.AccountManagement.ADStoreCtx..ctor(DirectoryEntry ctxBase, Boolean ownCtxBase, String username, String password, ContextOptions options) at System.DirectoryServices.AccountManagement.PrincipalContext.CreateContextFromDirectoryEntry(DirectoryEntry entry) at System.DirectoryServices.AccountManagement.PrincipalContext.DoLDAPDirectoryInit() --- End of inner exception stack trace --- at System.DirectoryServices.AccountManagement.PrincipalContext.DoLDAPDirectoryInit() at System.DirectoryServices.AccountManagement.PrincipalContext.DoDomainInit() at System.DirectoryServices.AccountManagement.PrincipalContext.Initialize() at System.DirectoryServices.AccountManagement.PrincipalContext.get_QueryCtx() at System.DirectoryServices.AccountManagement.Principal.FindByIdentityWithTypeHelper(PrincipalContext context, Type principalType, Nullable`1 identityType, String identityValue, DateTime refDate) at System.DirectoryServices.AccountManagement.Principal.FindByIdentityWithType(PrincipalContext context, Type principalType, String identityValue) at System.DirectoryServices.AccountManagement.UserPrincipal.FindByIdentity(PrincipalContext context, String identityValue)

我的方法:

public List<string> GetUserInfo(string user) {
        var list = new List<string>();

        using (var context = new PrincipalContext(ContextType.Domain, "xxxx.xxxx.xxxx:636", "DC=xxxx,DC=xxxx,DC=xxxx", ContextOptions.SimpleBind | ContextOptions.Sealing | ContextOptions.SecureSocketLayer)) {
            var uP = UserPrincipal.FindByIdentity(context, IdentityType.SamAccountName, user);

            //Do stuff with uP
        return list;
    }

但这工作正常:

public bool ValidateCredentials(string username, string password) {
        using (var context = new PrincipalContext(ContextType.Domain, "xxxx.xxxx.xxxx:636", "DC=xxxx,DC=xxxx,DC=xxxx", ContextOptions.SimpleBind | ContextOptions.Sealing | ContextOptions.SecureSocketLayer)) {
            return context.ValidateCredentials(username, password);
        }
    }

为什么我不能使用带 SSL 的上下文来处理 UserPrincipal？如果我删除 SSL 它工作正常..

Answer 1

我将 ContextOptions 更改为协商和 SSL。然后就成功了
