Chip -

I guess I am confused about what you are trying to do...

Do you want:
a) submit jobs from windows that will run on linux machines
b) submit jobs from windows that will run on windows machines
c) both a and b

In all cases you want the job to run as the user who submitted the job, 
correct?

If the answer is (a), you don't need the credd - the condor_credd is 
strictly something to help Windows execute machines run jobs as the 
submitting user.  However, you do need a way to know that login A on 
windows is the same person as login B on linux.  Does A = B ?  In other 
words, is user "fred" on Windows have a login name of "fred" on your 
linux machines?  Or is the mapping not that simple?

If the answer is (b), you then indeed need the credd.

If the answer is (c), you then need the credd for part (b).

I can try to help more once you clarify what you are trying to do ....

thanks,
Todd
