Any idea anyone on how to logon to such domain from knoppix ?

Purpose is to have one authentification process which is used for every application which knoppix uses.
For example terminal services client,citrix client,oracle client,acessing network printers,etc... .
For windoze this must only done 1 time. At logon.. .
For knoppix... ,for each application.... .
Knoppix could indeed be used as a transition to a fully linux enviroment.
Boot your pc with knoppix,when encountering a serious problem removed the cd and boot normally again. (or visa versa).
Maybe an idea for a customized knoppix ?
greetzzz,
