[R] problem with logistic regression

we try to do a logistic regression with the function glm. But we notice that this function don't give the same results as the SAS proc catmod (differents estimate given).
We try to change the contrast on R system with:
> options(contrasts=c(unordered="contr.SAS",ordered="contr.poly"))

We also try with brlr and logistf functions. Unfortunately, the estimate aren't still the same.

Please could someone help us.

Thank you
