URL to the bug?

Please follow the naming rule
https://google.github.io/styleguide/cppguide.html#Constant_Names

[Roman Sorokin (ftl), 2016/10/24 16:50:34]

Done.

+const char* objPath = "/org/chromium/authpolicy/Domain";

[hashimoto, 2016/10/24 03:01:18]

This should be const char[].

[Roman Sorokin (ftl), 2016/10/24 16:50:34]

Done.

+const char* authInt = "org.chromium.authpolicy";
+const char* domainInt = "org.chromium.authpolicy.Domain";
+const char* joinMethod = "Join";

[hashimoto, 2016/10/24 03:01:18]

Add a blank line.

[Roman Sorokin (ftl), 2016/10/24 16:50:34]

Done.

[hashimoto, 2016/10/24 03:01:18]

nullptr instead of NULL.

[Roman Sorokin (ftl), 2016/10/24 16:50:34]

Done.

Please move this pipe creation/preparation logic out of this class.

What does this "1" mean?

Have not defined error codes yet. For now it's just |not success|
