Comment 34 for bug 1372482

This is the same as what I am getting. However, it is only with a samba 4
machine on CentOS 7. My other samba 3 systems are working just fine. To make
my issues worse, yesterday I setup a new CentOS 7 machine and I cannot access
any of it's samba shares.... not in Ubuntu or in Windows!
In windows it says: The security ID structure is invalid.

Which makes me think it's an error similar to what we are seeing in this
kernel when it says: send length mismatch.

Maybe this is a samba 4 issue? Just my thoughts.
