HANA XS Engine Logon Error - with Resolution

[shaji_narayanan]

Overview:

Sharing an HANA XS access issue I faced recently on one of the HANA standalone appliance box.

Issue:

Unable to login to XS Administration Tool, or any other HANA XS application for that matter. 

Simulate the error:

• Access the XS engine URL http://<hostname>:<port>/sap/hana/xs/admin
• Enter user credentials.

Once the user-credentials are entered and clicked on button Login, nothing happens.  The browser hangs.. 

Error Analysis:

Use Chrome's Developer tool to capture error; in my case got following error:

http://<hostname>:<port>/sap/hana/xs/formLogin/login.xscfunc 500 (Internal Server Error)

• Apart from this very generic error, I was unable to find any other traces / error logs.
• User-id has all relevant (and probably more!) XS roles.

Resolution:

• Refer SAP Note 2039240
• In HANA configuration ini file xsengine.ini --> for parameter application_list --> add value libxsauthenticator
• In my case this did not work, as not all other parameters were present.  Hence, restored the default value of the parameter
