Solution Verified - Updated -

Issue

  • Batch/background jobs need to start and access krb protected fileystem
  • If the job runs and the ticket has expired access will be denied to the filesystem mount.
  • Looking for a way that the TicketGrantingTicket (TGT) can be renewed without having to enter a password.
  • I have an application, how can it automatically aquire TGT?

Environment

  • Red Hat Enterprise Linux (RHEL)
  • kerberos, i.e. provided by Red Hat Identity Management (IdM)
