What the GSS code is trying to do is create an account for itself to use on the domain, and adjust that account's permissions. To do this it's using the ADSI scripting APIs against the domain controller you specify.
That number is the decimal form of the error code, which in hex is 80070539 - this tells us that the error is a Windows error code called ERROR_INVALID_SID (the leading 8007 is how Windows error codes get wrapped up for COM, and the 0539 is the hex version of 1337 which is the underlying Windows error code).
So, this error code is a Windows error which is occurring internally to the ADSI libraries that Microsoft provide for manipulating Active Directory (which is a COM-based API, which is why the error number is coming out this way).
However, that doesn't explain what the error number means, because that's not exactly well-documented. There seem to be a variety of circumstances which can generate it, but it's impossible to tell which might apply.
Some are due to internal problems in Windows, as documented in e.g.
this MS KB article. The above MS KB article seems the most applicable thing I've found, since using the ADSI C++ interfaces is what our code is doing, but it doesn't really give any way to resolve the problem. I've never seen a situation where it occurs myself to know whether this is a configuration issue with AD or something else, since I've not seen a trace of the activity.
