Hum, this is weird, things work fine here (12.04) with MIT Kerberos:
superuser@Enzo:~$ su - vhann
Password:
vhann@Enzo:~$ exit
déconnexion
superuser@Enzo:~$ kadmin -p kadmin/admin
Authenticating as principal kadmin/admin with password.
Password for kadmin/admin@PARENTS.LOCAL:
kadmin: modprinc
Hum, I also tested with the 'modprinc -pwexpire 2011-12-01 vhann'
syntax. Both works. That being said, my KDC/kadmind server is MIT
Kerberos too.
