MIT Kerberos V5

Hi,

I would like to install Mit Kerberos v5 with Solaris 10. I should create the keytab file. But I don't know what's the meaning of the next parameter :

ktutil --> addent

addent -password -p principal -k kvno -e enctype

what's the value of "principal", "kvno" and "enctype" ?

Thank's in advanced
