Hello, We are running Samba 2.0.4b2 with the following configuration. -hershey1 (SCO UnixWare 7.1 Samba PDC server) -netpc2 (NT WKS4 client of the PDC's domain) -eventually other Win 9X, NT clients... In DIAGNOSIS.txt, test 3 fails like this : # smbclient -L hershey1 ... session request ok write_socket(3,168) write_socket(3,168) wrote 168 read_with_timeout: timeout read. EOF from client. receive_smb: length < 0! client_receive_smb failed ... protocol negotiation failed I looked in the source code and it fails in the /lib/util_sock.c because : "We got EOF on the file descriptor". This is where len read_smb_length_return_keepalive(fd, buffer, timeout) is returning len < 0. Samba works well to map drives but wait for a LONG period of time at Win NT WKS4's login to the PDC or shutdown. When trying to change password with Ctrl+Alt+Del, it fails when unix passwd synch = yes with the following /var/log.netpc2 : [1999/06/09 05:54:55, 10] smbd/chgpasswd.c:(189) Invoking '/usr/bin/passwd goulet' as password change program.

I know the passwd program can't be NIS because it requires the old password but has anybody made a script to change the passwd.byname.pag password entry to xxxxxxxxxxxxx and enter an empty password at the yppasswd old password entry so the total full duplex password synchronisation between UNIX and Windows with NIS and Samba can be possible?
