commit 91a5b8561e2f13f77fa5648f7cc373aff1701954
Author: Jeremy Allison <jra at samba.org>
Date:   Tue Sep 8 16:22:46 2009 -0700

    Fix bug 6673 - smbpasswd does not work with "unix password sync = yes". Revert change from 3.3 -> 3.4 with read_socket_with_timeout changed from sys_read() to sys_recv(). read_socket_with_timeout() is called with non-fd's (with a pty in chgpasswd.c and with a disk file in lib/dbwrap_file.c via read_data()). recv works for the disk file, but not the pty. Change the name of read_socket_with_timeout() to read_fd_with_timeout() to make this clear (and add comments). Jeremy.
