I was trying to change the default domain policy with GPME and it was
writing to Sysvol

OK, read that as 'altering the password attributes in AD', which is
what samba-tool does.
Or to put it another way, you change a password setting in GPME, this
results in the default domain policy GPO in Sysvol being updated, so

and alter the required attributes in AD.
