krbservicesetup is used by sso_util to configure Kerberized services on the current host. It uses kadmin to add service principals to the KDC database and create the krb5.keytab file. And then edits/creates the config files of the given service to use the proper service principal. krbservicesetu knows how to configure the FTP, AFP, POP, IMAP, SMTP and SSH services shipped by Apple in Mac OS X 10.3. krbservicesetup takes either a service_type, service_principal pair or a plist file with a list of services to configure.
