I tried to use "kinit -k -t keytab_file principal" to get a TGT in a windows scripts. So the job can be done without typing password. But the keytab file can only be created by kadmin in Unix. kinit(From MIT 2.1.1) complains the Unknow key tab file format. Does anyone know how to get a windows format keytab file? Thanks a lot Dennis Qiu
