Hello, if a do a "smbencrypt ä" then the output for the NT hash is "B5CF5E386433C7CB69E43ED774717792" but the correct hash would be "3104EAB484D59EFABCEA2C44B07F41D3". (If you do not see the letter: It is a small "a" with two dots, unicode code point 00E4.) Similar results hold for other umlauts, too. My Freeradius version is 2.2.0 running on Linux 3.8.13 with system locale set to en_US.utf8. I wrote an own utitly to calculate NT hashes to fill the Radius database. While I compared the results of my own utility with those from "smbencrypt", I found these discrepancies. In order to check which result was the correct one, I took a Windows computer, added a dummy user to it and set the passwords in concern. Then I extracted the NT hashes from the SAM database. One note of caution: If you take a web site like http://www.onlinehashcrack.com/hash-calculator.php, do not trust it. If it comes to non-ASCII letters the output is false, too.
