Subject: cracking MD5 hashes more than 8 characters long with a dictionary

Dear all,

I tried to use John 1.7.3-1 Pro against a shadow file with MD5 (FreeBSD) 
hashes. This shadow contains some hashes that are longer than 
8-characters. I create a custom wordlist, that contains the actual 
passwords included in this shadow.  When I try to crack this shadow 
using this custom wordlist, it cracks the passwords whose length is 8 
characters or less, but not the ones whose length is more than 8 
characters (although I feed the wordlist with the correct passwords)

Using exactly the same passwords and wordlist against a Blowfish shadow, 
John successfully cracks all the passwords, even the ones whose length 
is more than 8-characters.

I tried to change maxlength of john.conf to 16, but this didn't hep me.

Any ideas?

Thanks in advance
