No problem. Carry on. Small private network, nothing really valuable or
confidential on it, no regulatory hassles if the machines get pwned, no
customers to sue you - the perfect use case for identical users and
passwords on all machines. Convenience wins hands down.

A Black Hat getting access to one and then access to all would be a bad
thing if any of the above did not apply, though...

Security is rarely black and white; it's a mass of interconnecting
tradeoffs. But sharing passwords between accounts, even accounts owned
by the same person, is a bad idea *in general*.
