KeyError: 'getspnam(): name not found'
People can be confused. How could the name not found if the name actually
exists?
Attached the patch to differentiate the error whether the error is really 'name
not found' or 'permission denied'.
I use the error message from the getspnam manual:
http://man7.org/linux/man-pages/man3/getspnam.3.html
There is another error message from getspnam beside EACCES (permission denied),
which is ERANGE, but I don't think we need to handle this.
