Problem in Customizing the Logon User Interface

Hi All,

Can somebody plz help me in customizing the logon page of SAP EP6.0. I am using EP6.0 SP9. I have already modified the com.sap.runtime.logon.par.bak and renamed it after modification as my.new.logon.par. I am ready to save it back to the PCD directory on EP server but i am unable to find the authschemes.xml.bak, where i have to make further modification for passing the reference of this new par file. Can someone guide me the path of authschemes.xml.bak file in EP6.0 SP9 or if this file doesnt exist there which is the alternative file for passing the reference of this new my.new.logon.par file.

Thanking you in advance.

Regards,

Sarabjeet.
