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 princ@REALM.COM 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 princ@REALM.COM 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.
