Colleagues, 

I am running heimdal-0.6.3 on a FreeBSD 4.9-RELEASE system. Kerberized
FTP logins from other systems fail with the following error:

 ftpd[51877]: <--- 220 admin.sibptus.tomsk.ru FTP server (Version 6.00+Heimdal 
0.6.3) ready.^M - 
 ftpd[51877]: command: AUTH GSSAPI
 ftpd[51877]: <--- 334 Send authorization data.^M - 
 ftpd[51877]: command: ADAT YIICNwYJKo [deleted]
 ftpd[51877]: gss_accept_sec_context: Decrypt integrity check failed
 ftpd[51877]: <--- 431 Security resource unavailable^M - 

The kerberized telnet to the same host works perfectly (both
authenticates and encrypts), so I assume the server keytab file is OK:

# ktutil list
FILE:/etc/krb5.keytab:

Vno  Type           Principal                                   
  2  des-cbc-crc    host/[EMAIL PROTECTED]
  2  des-cbc-md4    host/[EMAIL PROTECTED]
  2  des-cbc-md5    host/[EMAIL PROTECTED]
  2  des3-cbc-sha1  host/[EMAIL PROTECTED]

krb4:/etc/srvtab:

Vno  Type         Principal                                   
  2  des-cbc-md5  host/[EMAIL PROTECTED]
  2  des-cbc-md4  host/[EMAIL PROTECTED]
  2  des-cbc-crc  host/[EMAIL PROTECTED]

What can be causing the problem? 
Thanks in advance for any input.
