I'm misunderstood here .. what I meant is why bothering with files to check passwords and users when you have the possibility to use somewhat powerfull security meshanism of MySQL DBMS. There are tabels like user, db, host, etc ... which brings ease to administration of privileges. The problem was to solve how to read and check and write passwords so that there would be no problem. One solution is locking, but why bother when the problem is completely solved in MySQL?! If I did it, and there are many users with different passwords, anyone can do it! 
use DBI;
use CGI qw(param);

my $username = param("password");
my $password = param("username");

my $dbh = DBI->connect("DBI:mysql:database=$mydatabase",$username,$pas
+sword);
print "<HTML><BODY>Woo this is wrong, you typed for user: $username pa
+ssword: $password and it seams that there is no such thing!</BODY></H
+TML>" if !$dbh;

so, as you can see it will display the error message if the script could not connect to database using provided password and username .. its that easy .. no need to break your head with locking problem, which is absolutly unecesary here! of course, you have to have two fields called "password" and "username" in you form and submit them to Perl script My reputation is -18 for this answer .. what does that mean?
