I havent got it runnig under sme. There seem to be only binaries for Debian available. AFAIK the RedHat-binaries are only for testing. You have to build a changeroot-environment where you can run it.
BTW: Theres a billworkgroup-5-client Version available from easygate(free for private use). It seems to have vpn and web-support for three webpages. You only have to buy the client-apis, if you want full outlook-support. If you have any 350 MHz box with 128 MB RAM available, check it out.
