the MD5-password? Probably due to new line effect. I created it using php's md5 function (<a href="http://php.net/manual/en/function.md5.php">http://php.net/manual/en/function.md5.php</a>)</div><div><br></div><div><div>

Hi folks,<br>
<br>
Been trying to look for information on this but haven't been able to find anything, prompting me to turn to the mailing list for help.<br>
<br>
In the event of using salted md5 hashes for passwords, where exactly does one store the salt?</blockquote><div><br></div><div>In the beginning of the password.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
There doesn't seem to be a place within the FR config to do that. Any advice would be much appreciated.<br>
