            ================

If I run ldapmodify & co from a script, I don't want to use '-W password'
because the password shows up in the output of 'ps' for everyone,
and I can't pipe the password to 'ldapmodify -w' because -w uses
getpassphrase() which reads from the tty instead of stdin.
So I added '-y file' which reads the password from file.  The programs
exit if the file cannot be read.

[Complete contents of file is used as password.  Use:
	echo -n "secret" > password
to create a file with "secret" as the password.  The -n avoids
adding a newline (which would invalidate the password).  Note
that echo is a builtin and hence its arguments are not visible
to 'ps'.]

I changed ldapmodify, ldapmodrdn, ldapdelete, ldapsearch, ldapcompare.
I did not bother to change ldappasswd and ldapwhoami, because they
prompt for many passwords.  [I fixed up ldapwhoami.]

Rerun autoconf after applying this patch. [Done.]

Note:  I do not know if Windows NT has fstat(), so I set HAVE_FSTAT to
undef in portable.nt.  (fstat() is used to warn if the file is publicly
readable or writeable.)  [I used fstat() to set the buffer size to
read.]

[Note: using the contents of a file extends the tools to support
passwords which could not normally be provided using getpassphrase()
or via the command line.]

Patch suggested by Matthew Backes <lucca@csun.edu>

Coverted LDAP_LOG macro to use subsystem ID int values instead of string values

Version: head
OS: SuSE Linux 7.3
URL: ftp://ftp.openldap.org/incoming/norbert.klasen.rejects.20020605.patch
Submission from: (NULL) (62.104.216.66)

This patch adds an '-S' option to ldapmodify. If a filename is specified with
this option, records which could not successfully be added/modified/deleted from
the LDAP server will be written to the specified file. Most useful in
conjunction with '-c' option.

Adapted .Sahalayev@pgr.salford.ac.uk's submission.
Needs to be extended to support comma separated list of options
	for other controls and such.

Here are fixes for more places where the argument to ctype.h functions
should be in the range of `unsigned char'.

Explanation of the last patch (to schema_init.c:bvcasechr()):
TOLOWER() and TOUPPER() return values in the range of `unsigned char',
but bvcasechr() then compares those values with a plain `char'.  So I
convert the return values from TOLOWER()/TOUPPER() to `char' first.

maildap could address buf[-1] if len was < 2.

REWRITE_SUBMATCH_ESCAPE is '%', not '\'.

librewrite and saslautz could walk past the end of a string which
ended with an escape character.
