The Kerberos database on the master KDC contains all of your realm's Kerberos principals, their passwords, policies, and other administrative information. To create and delete principals, and modify their attributes, you can use the kadmin(1M) or gkadmin(1M) commands.
The kadmin command provides an interactive command-line interface that enables you to maintain Kerberos principals, policies, and keytabs. There are two versions of the kadmin command: kadmin, which uses Kerberos authentication to operate securely from anywhere on the network, and kadmin.local, which must be run directly on the master KDC. Other than kadmin using Kerberos to authenticate the user, the functionality of the two versions is identical. The local version is necessary to enable you to set up enough of the database to be able to use the remote version.
Also, provided with the SEAM product is the SEAM Administration Tool, gkadmin, which is an interactive graphical user interface (GUI) that essentially provides the same functionality as the kadmin command. See "SEAM Administration Tool" for more information.
