【问题描述】：
我有一个 gitosis 服务器在工作，我也将 github 用于个人项目，我试图为两个帐户使用相同的公共和私有 ssh 密钥，唯一的区别是 gitosis 中的用户名是 md.mercado49 和在 github 中是 maumercado。
我已经将我的公钥上传到了 gitosis，当然我在 github 上已经有一段时间了，现在的问题是我在尝试连接到 gitosis 服务器时权限被拒绝，但是在使用 github 连接到 github 时它成功了相同的键。
这是我使用 ssh -vT gitosis@repocomit.virtual.uniandes.edu.co 命令得到的结果：
OpenSSH_5.6p1, OpenSSL 0.9.8r 8 Feb 2011

是否有可能做我想做的事，使用相同的密钥和不同的用户名和电子邮件进行身份验证？
我应该为其他帐户生成不同的密钥吗？如果可以，如何？
感谢大家的帮助！
...另外，我相信无关紧要，但谁知道呢，我用 github 信息设置了 git global config，但是在我有 git config --local 的公司的项目上...这应该没问题吧？
==== 更新 ====
所以我在调试部分注意到以下内容：
debug1: Offering RSA public key: /Users/maumercado/.ssh/id_rsa
debug1: Authentications that can continue: publickey
debug1: Trying private key: /Users/maumercado/.ssh/id_dsa
为什么在它实际上是私钥的情况下将 id_rsa 作为我的公钥，而在我的私钥甚至不存在时将 id_dsa 作为我的私钥？
