kinit error "Can't find client principal <username>@<domain> in cache collection"

[MathiasR111]

Hi,

We're running RunDeck in Linux using a service account. This means any kinit run is cached in the same file location (currently /tmp/krb5cc_UID) with the service accounts UID in the file name. If several Jobs were run at the same time there is a problem with the cache content.
Error: Can't find client principal @ in cache collection"

I've tried to include the RunDeck job username into the cache file path but I couldn't make it working. I've also tried to use the '-c' command line option for kinit in the plugin configuration what ended also in a not working kerberos authentication. I couldn't find any further documentation about how to configure kinit in the plugin settings properly.

Can you please help?

br,
Mathias

No one ever tried to run multiple Jobs at the same time to different Nodes while using Kerberos?
