CSDK 3.70 acessing Informix 11.70.FC1

Hello. I have a windows with csdk 3.70.TC1, connecting to a linux_64 running Informix 11.70.FC1GE just fine, via OLEDB or ODBC. But when I try to use the Ilogin application, it just raises the sql -1829 error. I´ve even tryed to reinstall the csdk, on a directory path with no spaces, eg: C:\\\\Informix\\\\csdk_370TC1\\\\ Our INFORMIXDIR is configured just fine: INFORMIXDIR=C:\\\\Informix\\\\csdk_370TC1\\\\ But the issue remains. Does anybody faced the same error above? (obs: if I try to connect Ilogin with csdk 3.50.TC7 on a linux_64, with Informix 11.50.FC6W1, it works just fine). Is it a client defect, maybe? Thanks a lot!
