Random error : Invalid credential was supplied - No credentials cache found

[kevinpemonon]

Hello,

Rundeck is installed in version 5.4.0 on a Debian 10 server.

We use the py-winrm-plugin-2.1.3 python module to target machines running Windows.

When executing a job, we randomly get this execution error. When we rerun the job on the same host, sometimes the job works, sometimes it doesn't, and we don't know why.

This is the error we get:

kerberos.GSSError: (('Invalid credential was supplied', 655360), ('No credentials cache found (filename: /tmp/krb5cc_112)

Do you have any idea of the cause of the error and how to resolve it?

Thank you for your help,

Kevin Pemonon
