Question

我已经基于CredentialsAuthProvider为LDAP（活动目录）创建了自定义身份验证提供程序。在文档之后，我重写了TryAuthenticate和OnAuthenticated，最后返回true。我也尝试了不使用OnAuthenticated。

我为OrmLiteAuthRepository使用UseDistinctRoleTables，并且在表中发现在UserRole中正在创建角色。

但是我遇到了异常：ArgumentNullException。字段名称“ s”。

"stackTrace": "[Authenticate: 20/03/2020 16:46:30]:
[REQUEST: {provider:Credentials,userName:xxxx,password:yyyy}]
System.ArgumentNullException: Value cannot be null.
Parameter name: s

我已经删除了代码。在Startup.cs中：

Plugins.Add(new AuthFeature( () => new AuthUserSession(),
            new IAuthProvider[] {
                new LdapCredentialsAuthProvider(AppSettings),

问题是ServiceStack的table <- data.frame(matrix(ncol = 10 , nrow = 11, dimnames=list(c("Number 1", seq(2,11,1)), seq(0,9,1))), check.names=FALSE) datatable(table, rownames=TRUE, class="compact", fillContainer = F, options =list(dom = "t", ordering = F, autoWidth = TRUE)) %>% formatStyle(columns=0, textAlign="right")试图填充AuthenticateService角色和权限，但是您的自定义AuthProvider并未填充AuthenticateResponse，后者用于查询Auth Repository中的角色

该解决方案是让您的自定义AuthProvider使用经过身份验证的用户的ID填充会话session.UserAuthId。

您还可以通过设置UserAuthId来禁止ServiceStack尝试填充角色/权限来防止此异常，例如：

IncludeRolesInAuthenticateResponse=false

在下一个ServiceStack v5.8.1 now on MyGet中，如果未填充Plugins.Add(new AuthFeature( () => new AuthUserSession(), new IAuthProvider[] { new LdapCredentialsAuthProvider(AppSettings), }, "/login.html" ) { IncludeRolesInAuthenticateResponse = false, });，它将不会尝试尝试检索角色，但是您的Custom AuthProvider应该仍然使用经过身份验证的用户的唯一ID来填充它。 / p>

ArgumentNullException与ServiceStack中的自定义身份验证提供程序
