# Short-Description:    MIT Kerberos KDC administrative daemon
# Description:          Starts, stops, or restarts the MIT Kerberos KDC
#                       administrative daemon (kadmind).  This daemon answers
#                       requests from kadmin clients and allows administrators
#                       to create, delete, and modify principals in the KDC
#                       database.
