Hi All,
I have performed all the steps mentioned in presto guide (
https://trino.io/docs/current/security/server.html) to implement kerberos authentication.
Also, as per my knowledge have correctly configured the krb5.conf, as the tickets are generating successfully
[ PROD root@ZMLPZCNVSAPD06 /home/canvas]# klist
Ticket cache: KEYRING:persistent:0:krb_ccache_JzVp1Mb
Default principal: presto@ZMLPZCNVSAPD06
Valid starting Expires Service principal
03/19/2021 06:58:54 03/20/2021 06:58:54 krbtgt/ZMLPZCNVSAPD06@ZMLPZCNVSAPD06
But the query over presto throws following error:
Error running command: Authentication failed: Invalid Token io.prestosql.client.ClientException: Authentication failed: Invalid Token
at io.prestosql.client.StatementClientV1.requestFailedException(StatementClientV1.java:470)

at io.prestosql.cli.Presto.main(Presto.java:31)
Any possible solution or workaround for this?
