CAS AD LDAP 32错误

Question

当我尝试使用CAS进行登录时,我看到了这种情况,这是通过LDAP对AD进行身份验证.

SEVERE: Servlet.service() for servlet cas threw exception
javax.naming.NameNotFoundException: [LDAP: error code 32 - 0000208D: NameErr: DSID-031001E5, problem 2001 (NO_OBJECT), data 0, best match of:

到目前为止,我通过BindLdapAuthenticationHandler进行了身份验证,解析后,它生成了一个查询构建器,然后将其抛出.

我认为它在试图恢复属性时失败了.为什么remaining name '/'？

Answer 1

剩余名称是DN的一部分,实际上并未在DIT的某个级别找到.例如,当您搜索cn=johns,ou=marketing,dc=example,dc=com并ou=marketing,dc=example,dc=com存在但cn=johns内部不存在时,ou=marketing重新生成的名称将是cn=johns.

'/'看起来不像是有效的RDN.我建议验证您作为搜索基础传递的内容.很可能它是一个无效的DN字符串.
