You can duplicate a principal by using the gkadmin GUI. No command-line equivalent exists for this procedure.
After starting the GUI with the /usr/sbin/gkadmin command, click the Principals tab and select a principal to duplicate.
Click the Duplicate button. This action duplicates all of the attributes of the selected principal except for the principal name and password.
Specify a new name and password, then click Save to create an exact duplicate.
To modify the duplicate, specify values for the principal's attributes.
Three windows contain attribute information. Choose Context-Sensitive Help from the Help menu to get information about the various attributes in each window.
Typically, few users are privileged to administer the Kerberos database. If this new principal needs administrative privileges, continue with Modifying Principals' Kerberos Administration Privileges.
