Create a keytab for the user "kuser1". You can use the
kadmin.local command line interface to add principals and
create keytab files, as shown shown below.
Retrieve the keytab file into the client machine. Use TalendtSCPGet component or retrieve it manually with the UNIX
cp command.
In this example, cp command is used to move the keytab
file to the UNIX home directory of the "kuser1" user where it has the read
access to the keytab file.
