Enhance Tracing for SAP HANA SSO Issues

SAP HANA will not login and authentication failures and errors. To troubleshooting any login/authentication/sso issue user need to enable tracing

Normally I enable below tracing to get the required info

ALTER SYSTEM ALTER CONFIGURATION ('indexserver.ini', 'SYSTEM') set ('trace', 'authentication') = 'debug' with reconfigure;
ALTER SYSTEM ALTER CONFIGURATION ('indexserver.ini', 'SYSTEM') set ('trace', 'crypto') = 'debug' with reconfigure;
ALTER SYSTEM ALTER CONFIGURATION ('xsengine.ini', 'SYSTEM') set ('trace', 'authentication') = 'debug' with reconfigure;
ALTER SYSTEM ALTER CONFIGURATION ('xsengine.ini', 'SYSTEM') set ('trace', 'xssession') = 'debug' with reconfigure;
ALTER SYSTEM ALTER CONFIGURATION ('xsengine.ini', 'SYSTEM') set ('trace', 'xsauthentication') = 'debug' with reconfigure;

Reproduce the issue and collect the trace. After you collect all the necessary info you can run below command to disable the tracing.

ALTER SYSTEM ALTER CONFIGURATION ('indexserver.ini', 'SYSTEM') UNSET ('trace', 'authentication');
ALTER SYSTEM ALTER CONFIGURATION ('indexserver.ini', 'SYSTEM') UNSET ('trace', 'crypto');
ALTER SYSTEM ALTER CONFIGURATION ('xsengine.ini', 'SYSTEM') UNSET ('trace', 'authentication');
ALTER SYSTEM ALTER CONFIGURATION ('xsengine.ini', 'SYSTEM') UNSET ('trace', 'xssession');
ALTER SYSTEM ALTER CONFIGURATION ('xsengine.ini', 'SYSTEM') UNSET ('trace', 'xsauthentication');

Hope this helps,

Failed to get connections for connection [http://hostname:8000] using session locale [English]

Failed to get connections for connection [http://hostname:8000] using session locale [English].

I was trying to create a OLAP connection from CMC to HANA in BOXI4.1 SP6 for Analysis Office 2.x SSO setup and receive below error. All the server details verified and everything seems to be correct.

After doing some investigation I found that the issue is due to limitation in BI platform4.1 sp06 or lower.

It cannot able to connect to HANA in CMC because there is no data provider available.

Errors in MDAS log file
Creating a BICS application with alias [session-2:http://hostname:8000:dev:en_US:HTTP:CREDENTIALS:null]

Possible Solution: Upgrade to BI 4.1 SP07 or higher then you should be able to connect using HTTP provider.

Unable to Connect to Published Data Sources When Opening a Downloaded Workbook from Tableau Server

I recently upgraded Tableau server from 9.1.2 to 9.1.3 to fix an issue with Data Server Data source. After upgrade we found below issue during the testing.

While opening a downloaded workbook from tableau server we received “Tableau Server Sign In” but URL greyed out and also URL is not correct as it is replaced by host name.

Normally you should receive a prompt to log in to the Tableau server, instead the server name field default to http://localhost and is unavailable for edit.

When we try to connect we got following error and not able to connect to published data source.

Cannot connect to Tableau Server. Please check the server name and port and try again. Internet communication error: SSL peer certificate or SSH remote key was not OK (analysis-server1)

It looks like the tableau server is not configured to recognize all the alias host names used to connect to the server. I have followed below steps to update the URL and port and able to resolve the issue.


1. Open command prompt as an administrator and go to the Tableau Server bin folder.
cd C:\Program Files\Tableau\Tableau Server\9.1\bin

2. Run the following command:
tabadmin set gateway.public.host "name"

where name is the URL used to connect to Tableau Server. For example:
tabadmin set gateway.public.host "analysis.oracleracexpert.com" 

3. If Tableau Server is configured for SSL, you must also run the following command:
tabadmin set gateway.public.port 443

4. Apply the configuration changes, and restart Tableau Server using following commands
tabadmin config
tabadmin restart

If a load balancer or proxy is in front of Tableau Server, the headers are not set.  Please refer to the following Knowledge Base article for information on the required headers
