Unexpectedly, we are encountering authentication failures when utilizing keytabs on our servers, while password-based authentication remains operational.
When executing the standard kinit -kt princ.keytab [email protected] command, everything functions as expected. However, issues arise when manually navigating to HBase or HDFS functions, with the following error message being displayed:
"No valid credentials provided (Mechanism level: Failed to find any Kerberos tgt)"
When applying Python's exchangelib for connectivity RCW tests via kinit [email protected] with the future password, the process works seamlessly, allowing usage of both HDFS and HBase.
Attempts to manually create new keytabs have not resolved the issue, yielding the same results. A klist command returns correctly, confirming that I have a valid TGT ticket.
