您需要一个自定义身份验证器,该身份验证器将尝试访问您的 Active Directory,如果通过身份验证,将查看 Grails 属性以检查用户名是否允许登录。
这是我使用的类。我更改了代码以验证配置:
class ActiveDirectoryAuthenticator {
private DefaultSpringSecurityContextSource contextFactory
private String principalSuffix = ""
def grailsApplication
public DirContextOperations authenticate(Authentication authentication) {
// Grab the username and password out of the authentication object.
String principal = authentication.getName() + "@" + principalSuffix
String password = ""
if (authentication.getCredentials() != null) {
password = authentication.getCredentials().toString()
}
// If we have a valid username and password, try to authenticate.
if (!("".equals(principal.trim())) && !("".equals(password.trim()))) {
try {
String provider = contextFactory.getUrls()[0]
Hashtable authEnv = new Hashtable(11)
authEnv.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.ldap.LdapCtxFactory")
authEnv.put(Context.PROVIDER_URL, provider)
authEnv.put(Context.SECURITY_AUTHENTICATION, "simple")
authEnv.put(Context.SECURITY_PRINCIPAL, principal)
authEnv.put(Context.SECURITY_CREDENTIALS, password)
javax.naming.directory.DirContext authContext = new InitialDirContext(authEnv)
//here validate the user against your config.
if(!authentication.getName() in grailsApplication.config.adUsersAllowed) {
throw new BadCredentialsException("User not allowed.")
}
DirContextOperations authAdapter = new DirContextAdapter()
authAdapter.addAttributeValue("ldapContext", authContext)
return authAdapter
} catch ( NamingException ex ) {
throw new BadCredentialsException(ex.message)
}
} else {
throw new BadCredentialsException("Incorrect username or password")
}
}
public DefaultSpringSecurityContextSource getContextFactory() {
return contextFactory
}
/**
* Set the context factory to use for generating a new LDAP context.
*
* @param contextFactory
*/
public void setContextFactory(DefaultSpringSecurityContextSource contextFactory) {
this.contextFactory = contextFactory
}
public String getPrincipalSuffix() {
return principalSuffix
}
/**
* Set the string to be prepended to all principal names prior to attempting authentication
* against the LDAP server. (For example, if the Active Directory wants the domain-name-plus
* backslash prepended, use this.)
*
* @param principalPrefix
*/
public void setPrincipalSuffix(String principalSuffix) {
if (principalSuffix != null) {
this.principalSuffix = principalSuffix
} else {
this.principalSuffix = ""
}
}
}
在 resources.groovy 中将其声明为您的 ldapAuthenticator:
ldapAuthenticator(ActiveDirectoryAuthenticator) {
contextFactory = ref('contextSource')
principalSuffix = 'domain.local' //your domain suffix
grailsApplication = ref('grailsApplication')
}
缺点是更改 config.groovy 时需要重新启动上下文
在您的控制器中,只需使用@Secured('IS_AUTHENTICATED_FULLY')
