Samba setup essentially as a PDC with encrypted passwords, when enabling "unix password sync", unprivileged users cannot change their password using the "smbpasswd" command, the following error is produced: [user@server /]$ smbpasswd Old SMB password: New SMB password: Retype new SMB password: machine 127.0.0.1 rejected the password change: Error was : RAP86: The specified password is invalid. Failed to change password for user If you turn off "unix password sync", then non-root users can then change their own passwords. I also note that trying to change your password from a Windows machine produces the same failure to change password when unix password sync is enabled. I have tested this on a Fedora Linux Core 1 machine with Samba versions 2.2.8a and 3.0.2, and with 2.2.8a on a Red Hat Linux 7.3 machine and it produces exactly the same results. I double checked my smb.conf configuration with John Terpstra via the Samba mailing list and he commented that he can reproduce exactly the same problem himself and suggested I make this bug report. Thanks for your time. :)
