smbpasswd fails

[Jamie ffolliott]

Updated the latest CVS today (april 24) and got new behaviour..

In log.samba_server :
[1999/04/24 21:39:55, 3] smbd/chgpasswd.c:chgpasswd(381)
  Password change for user: jmeff
[1999/04/24 21:39:55, 0] lib/fault.c:fault_report(40)
  ===============================================================
[1999/04/24 21:39:55, 0] lib/fault.c:fault_report(41)
  INTERNAL ERROR: Signal 11 in pid 1002 (2.1.0-prealpha)
  Please read the file BUGS.txt in the distribution
[1999/04/24 21:39:55, 0] lib/fault.c:fault_report(43)
  ===============================================================
[1999/04/24 21:39:55, 0] lib/util.c:smb_panic(2538)
  PANIC: internal error

This happens by setting these options:
unix passwd sync = yes
passwd program = /usr/bin/passwd %u
passwd chat = *password* %n\n *password* %n\n *successfull*

No problems though if I set
unix passwd sync = no

Looks like the 'unix passwd sync' feature is broken.  Both smbpasswd and
SWAT will report "success" changing a user's password, but the password
doesn't actually change.  You'll notice the passwd hash doesn't change in
the smbpasswd file.  I'm not affluent enough to code a fix, so I'll post
this as a bug report.  Running redhat 5.2 kernel 2.2, and tested on a stock
Redhat 5.2 machine too.  If someone does post a fix, please copy a message
to this list.
Cheers,
Jamie
