Ah ha. This was the bit of info that caused the light-bulb to go off. My
theory is: The max number of connections is being reached on the Windows
domain controller your Samba server is authenticating against. Your Windows
admin needs to allow more connections on the AD DC.

The supporting evidence is:

- A quick google of 'No More Connections can be made to this remote
computer at this time because there are already as many connections as this
computer can accept'  reveals that this is a common error received by a
windows client trying to access a too busy windows server. I.e. it's a
windows error message.

- If the Windows AD server reaches a number of connections too high to
service any new ones, it makes sense that a) Nothing would show in AD logs,
as the connection never even completes, but b) you'd get a rejected
password message from Samba as RHEL simply gets nothing back from AD (the
connection never completes).
