配置SQL Anywhere以从ASE服务器读取

我有一个SybaseASE服务器,我可以用ASEISQL连接到它。我的sql.ini文件中的数据库定义如下:

[<NAME>]
master=TCP,<servername>,<port>

要连接ISQL,我可以进行以下命令行调用,它可以工作:

isql -U <username> -P <password> -S <NAME>

我的最终目标是为我正在编写的RIA服务使用SQL Anywhere的ADO.NET实体框架连接。我现在正试图通过SybaseCentral(而不是通过Visual Studio)使用SQL Anywhere进行连接,但无法使其正常工作。在“标识”选项卡下,我使用和作为凭据,并将下半部分保留为“无”,在“数据库”选项卡下,我指定服务器名称,在“网络”下,我选中“TCP/IP”,并指定为主机和端口。我得到以下错误:

如果我遗漏了重要的细节,我会提前道歉。我刚接触Sybase,有严格的Oracle背景。如果我遗漏了你需要知道的东西,请发表评论,我会更新问题。感谢您帮助Sybase新手。
