samba - Dec 2024 - Configuration file does not specify default realm

I have three Windows 10 boxes which I can successfully access
from Linux using xfreerdp with a command like, "xfreerdp /u:user
/v:machine:3389".  There is no local domain other than whatever the
default might be. There is no domain controller involved. xfreerdp
prompts for domain and password, I just hit enter on the domain
request and, after entering the password, I'm connected.

With winexe I can connect to two of them with a command like,
  "winexe -U .\\user%password //machine systeminfo".
But with the third, I get this response:
  "[ERROR][com.winpr.sspi.Kerberos] -
  [kerberos_AcquireCredentialsHandleA]: krb5_parse_name
  (Configuration file does not specify default realm [-1765328160])".
Some online references tell me to be sure the correct default domain
is in /etc/krb5.conf and, of course, there is no default domain
specified in that file. Clearly it isn't needed for the first two
Windows machines and I don't have a value to put in there anyway.

What could be the cause and/or solution in this case?

It sounds like you are trying to connect to three different Windows
machines from one Linux machine, is this correct ?

If it is correct and you can connect to two of them but not the third,
then surely the problem lies on the third Windows machine and has
nothing to do with Linux at all.

I would start by trying to find where your third Windows machine
differs from the two working ones.
