Full Discussion: Modifying a particulae data in a line contained in File
Top Forums UNIX for Dummies Questions & Answers Modifying a particulae data in a line contained in File Post 302359099 by TonyFullerMalv on Monday 5th of October 2009 07:49:57 PM

Something like this would do the trick:
Code:
sed '/userid/s/oldpasswd/newpasswd/' inputfile > tempfile && \
cp tempfile inputfile && \
rm tempfile

Where the /userid/ means that the sed statement will only replace (substitute) "oldpasswd" with "newpasswd" for the userid given and not any other.

Is that what you are after?

net::ldap::extension::setpassword

Net::LDAP::Extension::SetPassword(3pm)			User Contributed Perl Documentation		    Net::LDAP::Extension::SetPassword(3pm)

NAME

       Net::LDAP::Extension::SetPassword - LDAPv3 Modify Password extension object

SYNOPSIS

	use Net::LDAP;
	use Net::LDAP::Extension::SetPassword;

	$ldap = Net::LDAP->new( "ldap.mydomain.eg" );

	$ldap->bind('cn=Joe User,cn=People,dc=mydomain,dc=eg",
		    password => 'oldPassword');

	$mesg = $ldap->set_password( oldpasswd => 'oldPassword' );

	die "error: ", $mesg->code(), ": ", $mesg->error()  if ($mesg->code());

	print "changed your password to", $mesg->gen_password() , "
";

DESCRIPTION

       "Net::LDAP::Extension::SetPassword" implements the "Modify Password" extended LDAPv3 operation as described in RFC 3062.

       It implements no object by itself but extends the Net::LDAP object by another method:

METHODS

       set_password ( OPTIONS )
	   Set the password for a user.

	   OPTIONS is a list of key/value pairs. The following keys are recognized:

	   user
	       If present, this option contains the octet string representation of the user associated with the request.  Depending on how users
	       are identified in the directory this string may or may not be a DN according to RFC 2253.

	       If this option is not present, the request acts up upon the password of the user currently associated with the LDAP session.

	   oldpasswd
	       This option, if present, must contain the current password of the user for whom this operation is performed.

	       It depends on the server's implementation in which cirumstances this option is allowed to be missing.

	   newpasswd
	       If present, this option contains the desired password for the user for whom the operation is performed.

	       Depending on the server's implementation this option may be required by the LDAP server.

       gen_password ( )
	   Return the password generated by the server in response to the "set_password()" call when applicable. The server will not generate a
	   new password if "newpasswd" was passed to "set_password()".

	   This method is a method of the Net::LDAP::Message response object returned in reply to "set_password()" in case the "set_password()"
	   call succeeded.

	   By this method the caller can query for the value of the password in case he did not call "set_password()" with the "newpasswd" option.
