java ldap authenticationexception,LDAP错误代码 及解决方法
1. error code 53
===========================================================================
问题：创建新用户时出现数据后端异常
在 WebSphere Portal Express 中，您可以设置密码的最短和最长长度。如果设置的密码长度与 LDAP 服务器的策略不相同，则在创建用户时您可能会看到以下异常：
EJPSG0015E: Data Backend Problem com.ibm.websphere.wmm.exception.WMMSystemException:
The following Naming Exception occurred during processing:
"javax.naming.OperationNotSupportedException: [LDAP: error code 53 - 0000052D:
SvcErr: DSID-031A0FBC, problem 5003 (WILL_NOT_PERFORM), data 0
]; remaining name 'cn=see1anna,cn=users,dc=wps510,dc=rtp,dc=raleigh,dc=ibm,dc=com';
resolved object com.sun.jndi.ldap.LdapCtx@7075b1b4".
原因：这是由于“密码不能满足密码策略的要求”导致
解决方案：
1. 打开域安全策略-安全设置-账户策略-密码策略-密码必须符合复杂性要求。定义这个策略设置为:已禁用。/ 密码长度最小值：定义这个策略设置为0。
2. 打开域控制器安全策略-安全设置-账户策略-密码策略-密码必须符合复杂性要求。定义这个策略设置为：已禁用。/ 密码长度最小值：定义这个策略设置为0。
3. 最后运行刷新组策略命令为：gpupdate /force
===========================================================================
2. Need to specify class name
===========================================================================
javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial
原因：LdapContext在处理完上个环节被close(),LdapContext=null;
解决方案：不close;
3. error code 50
===========================================================================
javax.naming.NoPermissionException: [LDAP: error code 50 - 00002098: SecErr: DSID-03150A45, problem 4003 (INSUFF_ACCESS_RIGHTS), data 0
4. error code 68
===========================================================================
javax.naming.NameAlreadyBoundException: [LDAP: error code 68 - 00000524: UpdErr: DSID-031A0F4F, problem 6005 (ENTRY_EXISTS), data 0
原因：创建的用户已经存在了
7. No trusted certificate
===========================================================================
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: No trusted certificate found
1.cas机器A，A上a,b,c服务运行良好
2.website 位于B机器，cas可以截获请求，跳转javax.net.ssl.SSLHandshakeException
将A上生生成的客户端密钥，导入B
A运行
sudo keytool -genkey -alias tomcat -keyalg RSA -keypass changeit -storepass changeit -keystore server.keystore -validity 3600
$ keytool -export -trustcacerts -alias tomcat -file server.cer -keystore server.keystore -storepass changeit
$ sudo keytool -import -trustcacerts -alias tomcat -file server.cer -keystore $JAVA_HOME/jre/lib/security/cacerts -storepass changeit
B运行最后一句即可
建立信任关系，客户，服务密钥，客户多处
8. error code 1
===========================================================================
javax.naming.NamingException: [LDAP: error code 1 - 00000000: LdapErr: DSID-0C090AE2, comment: In order to perform this operation a successful bind must be completed on the connection., data 0, vece
原因：新增域用户的时候，ctx没有绑定管理员用户
解决方法：ctx.addToEnvironment(Context.SECURITY_PRINCIPAL, adminUser + "@" + ldapProperty.getDomain());
ctx.addToEnvironment(Context.SECURITY_CREDENTIALS, adminPwd);
9. error code 50
==========================================================================
javax.naming.NoPermissionException: [LDAP: error code 50 - 00000005: SecErr: DSID-03151E04, problem 4003 (INSUFF_ACCESS_RIGHTS)
原因：新建域用户时候，ctx绑定到一个普通用户(该用户没有新建用户的权限)
解决方法：使用管理员用户进行绑定：
ctx.addToEnvironment(Context.SECURITY_PRINCIPAL, adminUser + "@" + ldapProperty.getDomain());
ctx.addToEnvironment(Context.SECURITY_CREDENTIALS, adminPwd);
10. error code 19
==========================================================================
javax.naming.directory.InvalidAttributeValueException: [LDAP: error code 19 - 0000052D: AtrErr: DSID-03190F00, #1:
0: 0000052D: DSID-03190F00, problem 1005 (CONSTRAINT_ATT_TYPE)
原因：这个最大的可能是不满足域安全策略：如密码复杂性、密码最短使用期限、强制密码历史。即长度、包含的字符、多久可以修改密码、是否可以使用历史密码等。
11. LDAP: error code 50
==========================================================================
javax.naming.NoPermissionException: [LDAP: error code 50 - 00000005: SecErr: DSID-031A0F44, problem 4003 (INSUFF_ACCESS_RIGHTS)
原因:这个是最初代码使用的replace操作，这个在AD里对应的是密码重设(普通用户默认没有这个权限，管理员可以操作)，另外remove操作时提供的旧密码错误也可能报这个异常
12. RSA premaster secret error
==========================================================================
javax.naming.CommunicationException: simple bind failed: 172.18.20.4:636 [Root exception is javax.net.ssl.SSLKeyException: RSA premaster secret error]
原因：Tomcat 配置的JDK与添加证书的的JDK不一致。如：证书存放路径为C:/Java/jdk1.6.0_10/jre/lib/cacerts 而Tomcat 配置的JDK为C:/Java/jre6 ，使得两者路径不一致，SSL验证的时候，找不到证书
13.No trusted certificate found
==========================================================================
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: No trusted certificate found
原因：信任证书库文件路径不正确
解决方法：将正确工程中 /WEB-INF/classes目录下
14. error code 49
==========================================================================
javax.naming.AuthenticationException: [LDAP: error code 49 - 80090308: LdapErr: DSID-0C090334, comment: AcceptSecurityContext error, data 52e, vece
原因：用户名或密码错误
