[Samba] using unix password sync to sync krb5 password

[FM]

Hello,
I'm creating a perl script that will update a username password with
this syntax "
script.pl -u USERNAME

I had a weird idea :
unix password sync = yes
passwd program = /bin/scipt.pl -u %u
passwd chat = *new*password* %n\\n*new*password* %n\\n *ok_changed*

does someone try this type of little hack to sync krb5 DB ?

Thanks !
