想请问一下，所谓的管理员密码是刚安装时默认的密码：openpgpwd，还是我建数据库时输入的密码？

修改内容：
我修改了“Server\server\openerp-server.conf”文件中的
原始：pg_path = C:\Program Files\OpenERP 6.1-20120814-233345\Server\PostgreSQL\bin
修改为：pg_path = C:\Program Files\OpenERP 6.1-20120814-233345\PostgreSQL\bin

按照 [检测到链接无效，已移除] 替换了
“Server\server\openerp\tools\misc.py和misc.pyo”
“Server\server\openerp\service\web_services.pyo”
重启服务器后还是不行。

默认的密码是admin
