Your browser does not support SPNEGO. Authentication not possible

SPNEGO configuration for sap HANA XS application:

we have followed the guide for Single Sign-On with SAP HANA® Database using Kerberos and Microsoft Active Directory.

However,browserprompt.jpgstudio-authentication-error.jpgtracefile.jpg we face the below error when checking the xsengine trace files.

e Authentication MethodSpnegoInternalAcceptor.cpp(00048) : initialize failed - SPNEGO not provided by the lib

We have activated the SPNEGO authentication from Hana Admin Console.

    What revision are you using? With SP12 onwards the kerberos libraries are delivered with the installation, so the environment uses this automatically, so this error should not be occurring. If you are below SP12 then this depends on the OS you could just update to SP12, this would be the easiest open I guess.

    If you are on SP12 already then to get an idea of what is happening here then you would need to run the traces specified in the Troubleshooting SSO Kerberos Note

    Without these traces it will be impossible to know

      Hi Imtiaz,

      Thanks for your response, I've already done this configuration on FireFox but the error remains same.
