我不得不再次尝试解决Ldap的这个问题，请记住我的功能，再一次引起问题。
目前，我有支持Ldap身份验证的工作Grails 2.2.4应用程序，但是检查“记住我”选项会导致如下错误:

香港专业教育学院尝试了各种方法来解决这个问题，但我只是不了解它的本质。它为我提供了完整的零信息，指出可能出现的问题。
如果有人遇到类似的问题，我将为您提供一些线索。我想“记住我”来使用cookie。
ldap的配置请记住我:
grails.plugin.springsecurity.ldap.rememberMe.detailsManager.groupSearchBase='ou=LALALAL,O=LALALAL,C=LALALAL'
grails.plugin.springsecurity.ldap.rememberMe.usernameMapper.userDnBase='O=LALALAL,C=LALALAL'
grails.plugin.springsecurity.ldap.rememberMe.usernameMapper.usernameAttribute="SOME ID"
编辑可能需要的人:
问题是PersistentTokenBasedRememberMeService中的一行
UserDetails user = getUserDetailsService().loadUserByUsername(token.getUsername());
它想使用GormUserDetailsService检索有关User的数据，但是由于Ldap而失败。没有可以从中获取数据的数据库。
可能的解决方法是用自定义类替换UserDetailsService。
最佳答案
使用自定义UserDetails类和CustomPersistentTokenBasedRememberMeService进行了修复。
关于spring - Grails Ldap记住我IllegalArgumentException，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/21781191/
