NetWare5 has been shipping production code since September '98 (NDS with LDAPv2 since much before then, and plain NDS even longer). In fact, Novell was the one who offered their multimaster technology to the IETF when LDAPv3 was standardized, and the IETF decided that it wasn't worth their trouble (a major blunder which I will never understand). NT5 is in beta2, and not expected to ship in volume until 2nd half of 1999 as Windows2000. NT5 beta2's AD is in unusable state, constantly blowing up and otherwise hideous. When we went to Microsoft to get an eval they said they needed to bring an 8 way PIIXeon in to show it off. Thanks, but no thanks. Take a serious look at NetWare5 if you're shopping for a fast scalable (and may I add proven) multimaster LDAP directory. I don't trust slides either. That's why I am beating the crap out of directories in the lab. Cheers, Chris -- Frisbeetarianism, n.: The belief that when you die, your soul goes up on the roof and gets stuck.
