我正尝试使用samba4将RHEL6服务器join到域中。 networking广告join正常工作，join成员不过。 有效地，wbinfo –getdcname不起作用，因为wbinfo –dsgetdcname会。
如果能够区分这些命令之间的区别，那将是非常有帮助的。
Samba3上的联接成功，并且按照预期工作，除了嵌套组

对于它的价值，我只是有同样的问题，解决scheme是由RHEL6服务器使用的DNS服务器包含过时的信息。 _msdcs.DOMAIN区域中的信息与当前设置不匹配，导致_msdcs.DOMAIN失败。 刷新所有DNS服务器和本地DNScaching后，联接工作正常。 在24小时之后，这可能也会自行解决，这就是caching时间。
