k5passwd problem

[Someone]

Hello,

I am trying to change my password using k5passwd on my FreeBSD 4.5 
client and I get the following error:

bash-2.05a$ k5passwd
username at REALM's Password:
New password:
Verifying password - New password:
k5passwd: krb5_change_password: ASN.1 identifier doesn't match expected 
value

On linux kpasswd works fine... I am using Windows 2k as KDC, does anyone 
know what's wrong ?

Regards
