We are using open source version of rstudio-server installed on centOS 7 and connecting to it via a web browser http://servername.domain.com:8787.
I am doing a POC to connect to SAP HANA database using ODBC from the rstudio (via web browser). I keep getting this error:
Warning messages:
1: In RODBC::odbcDriverConnect("DSN=SAP_HANA_ODBC;UID=uid=db-user;PWD=pwd=secretpwd") :
[RODBC] ERROR: state HY000, code 10, message [unixODBC][SAP AG][LIBODBCHDB SO][HDBODBC] General error;10 authentication failed
2: In RODBC::odbcDriverConnect("DSN=SAP_HANA_ODBC;UID=uid=db-user;PWD=pwd=secretpwd") :
ODBC connection failed
By the way this connects fine from my Rstudio desktop.
We put a trace on the HANA ODBC tier and found this:
2020-11-20 11:16:58.347439 d [Authentication|ManagerInitiator.cpp:324] Method is not applicable: LDAP
2020-11-20 11:16:58.347459 d [Authentication|ManagerInitiator.cpp:258] Method is applicable: SCRAMPBKDF2SHA256
2020-11-20 11:16:58.347466 d [Authentication|ManagerInitiator.cpp:270] evaluate was successful for method: SCRAMPBKDF2SHA256
RStudio server is enforcing LDAP authentication as opposed Native authentication. BTW I am able to connect to HANA using the same ODBC connection via HANA sql client.
How do I enforce RStudio server to use the username/password mentioned at the command line:
> ch <- odbcConnect("SAP_HANA_ODBC","uid=db-user","pwd=secretpwd")
Thanks
