I am running a TSM upgrade to 2021.4 and I get an error saying "Preflight Check Exception : Could not establish connection to Active Directory" during the TSM upgrade script.
I am using Amazon Managed Active Directory. It is only operating on Port 389 at the moment. They have the option checked to allow unencrypted communication with Active Directory.
I found this link that seems to indicate there was a new 'Pre-Flight' check added to ensure Tableau was secure. This includes an LDAPS check to AD.
https://help.tableau.com/current/server/en-us/cli_configuration-set_tsm.htm#wgserver-domain
Additionally I tried the "--skip-preflight-check" flag and I am still having the same issue.
Any advice for getting around this error without having to turn on 'Client-Side LDAPS' in AWS Managed AD?
Thank you all very much!
Hi Justin,
Beginning with Tableau version 2021.2, Tableau Server no longer allows insecure connections with Active Directory. If your current instance of Tableau Server is communicating with Active Directory over a non-encrypted channel, upgrade will fail.
Run the following commands to allow an insecure connection on your current version of Tableau Server before you upgrade:
tsm configuration set -k wgserver.domain.allow_insecure_connection -v true --force-key
tsm pending-changes apply
