Enabling Kerberos in the sapgui for Java on Linux:

• This assumes you already have Kerberos working on the machine you run the sapgui on.

• Install the SAP GUI for Java. If you use a Debian based distribution, you can use the sapgui-package for that.

• Install a kerberos GSSAPI library, if not already there. On Debian you can e.g. use libkrb53.

• Before starting the sapgui tell it to use that library for for SNC:

  export SNC_LIB=/usr/lib/libgssapi_krb5.so.2
  

• Append these parameters to the connect string you use to connect to your SAP server:

  &sncname="p/krb5:SAPService/sapsrv.example.com@EXAMPLE.COM"&sncon=true&sncqop=9
  

  Substitue sapsrv.example.com with the SAP server. This server must have SNC via GSSAPI/Kerberos enabled. Replace EXMAPLE.COM with your Kerberos realm. More details on these parameters can be found in the manual.

• Connect either via guilogon or guistart while having a valid Kerberos ticket.
