Two comments. Firstly use RC4 (e.g. RC4-HMAC) not DES in your configuration
assuming you have a MIT Kerberos version > 1.3 (is HPUX 11i still based on
MIT 1.1.1 ?). If not you need to set the AD entry for unix_client to be DES
only. Secondly did you change the password of the unix_client user ? If not
please try to change the password once and re-extract the keytab.
