本文记录了LDAP6.3在DSCC控制台启动时遇到“意外错误”的问题及解决过程。通过日志发现连接绑定失败，并最终定位到/etc/hosts配置错误。修正主机名后，问题得以解决。

LDAP6.3在DSCC控制台启动实例完成，但是操作状态显示“意外错误”，查看日志如下：

检查发现/etc/hosts配置文件有错，127.0.0.1和::1后面的hostname写到其它服务器的主机名了。因为是/etc/hosts配置文件是从其它服务器直接复制粘贴过来的，所以就错了。修改为正确的，删除原来的实例，重新创建后正常。

# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 testldap210.com testldap210
::1 testldap210.com testldap210
