SonarQube 5.2，LDAP插件1.5：com4j.ComException

Question

從LDAP 1.4升級後無法進行AD登錄。在TRACE日誌中記錄以下錯誤消息：

DEBUG web[o.s.p.l.w.WindowsUsersProvider] Requesting details for user: xxxxxx 
ERROR web[rails] Error from external users provider: exception Java::Com4j::ExecutionException: com4j.ComException: 8007203a Failed to MkParseDisplayName : The server is not operational. : .\com4j.cpp:217 

從sonar.properties中刪除LDAP設置沒有幫助。降級到LDAP 1.4後，所有事情都可以再次運行。我們錯過了一些配置設置嗎？

Answer 2

Please go through the new changes and try the below mentioned settings. 

LDAP 1.5 plugin is using Waffle to support Windows Authentication and SSO on Windows OS. 
LDAP in Windows auth mode supports two ways of login from browser: 

1.Single sign On 
SSO will be performed on hitting any SonarQube url other than /sessions/login . 
Only domain users are supported through SSO. 

2.Form based login from /sessions/login page 
Domain users 
Login: <domain\alias> or alias@domain or alias 
Password: <domain credentials> 

Technical users 
Login: <username> 
Password: <password> 

On logout, users will be presented login page (/sessions/login), 
where he can choose to login as technical user or domain user by 
passing appropriate credentials. 

    For those users who are already using previous version of LDAP plugin to 
connect to Microsoft AD and have already defined authorization in terms of those 
users and group name use following settings in Windows OS: 


# LDAP configuration 
sonar.security.realm=LDAP 
ldap.windows.compatibilityMode=true 
sonar.log.level=DEBUG (For debugging purpose, remove this if you don't see any issue) 
ldap.windows.auth=true

Default protocol is NTLM which should work for most of the scenarios.

If you want to use Kerberos "Negotiate" protocol please use the following steps. 

Negotiate Authentication Steps: 
For negotiate authentication to work make sure following steps are followed: 
1.Browser Configuration 
Waffle link: Configuring Browsers (IE/Firefox)

2.Kerberos setup 
Make sure that user has privilege for Kerberos delegation 
setspn -L username 
To add preivileges to the current user run 
setspn -S HTTP/machine:port machine 
example: 
setspn -S HTTP/machine:9000 machine 

3.The SonarQube application is running as a service(NT service)
