to the report in:

Title:
  smbpasswd -r host -U user broken after samba update from 4.1.6 to
  4.3.9

Status in samba package in Ubuntu:
  Confirmed

Bug description:
  I am using smbpassword -i <remotehost> -U <user> to sync samba & linux password store in an LDAP - directory.
  This worked well until samba-4.1.6.
  In samba 4.3.9 ill get following error message:
  smb_signing_good: BAD SIG: seq 1
  Could not connect to machine <remotehost>: NT_STATUS_ACCESS_DENIED

  Downgrade to 4.1.6 brings password sync to work again:
  aptitude -y install samba-libs=2:4.1.6+dfsg-1ubuntu2 libsmbclient=2:4.1.6+dfsg-1ubuntu2 libwbclient0=2:4.1.6+dfsg-1ubuntu2 python-samba=2:4.1.6+dfsg-1ubuntu2 samba=2:4.1.6+dfsg-1ubuntu2 samba-common=2:4.1.6+dfsg-1ubuntu2 samba-common-bin=2:4.1.6+dfsg-1ubuntu2 samba-dsdb-modules=2:4.1.6+dfsg-1ubuntu2 samba-vfs-modules=2:4.1.6+dfsg-1ubuntu2 smbclient=2:4.1.6+dfsg-1ubuntu2 libldb1=1:1.1.16-1 python-ldb=1:1.1.16-1 winbind=2:4.1.6+dfsg-1ubuntu2 libpam-winbind=2:4.1.6+dfsg-1ubuntu2 libnss-winbind=2:4.1.6+dfsg-1ubuntu2
