Error "Unable to read keytab" When Validating Kerberos Keytab
When validating a Kerberos keytab, a "Validate Keytab server error: Unable to read keytab" error occurs.
Cause: The keytab might have been Base64-encoded twice. If the Vault secret format is set as plain-text, OCI Vault encodes the value for you.
Solution: When creating a secret in Vault, ensure that the keytab is in Base64 format and that you select Base64 as the secret format.
