OK. Time to summarise.
smb.conf on DC
samba version on DC
samba version on working print server
smb.conf on working print server
the DN of the user who trips the 'idmap ad' error (ute)
host <hostname of DC>
host <hostname of print server>
host <ip of DC>
host <ip of print server>
getent passwd ute
getfacl <path to share where ute is accessing>
With that we stand a chance.
