I have a server running NW6.0. I have 2 Macintosh clients, an iBook running OS X 10.4.11, and an old Performa running OS 8.1. On both of them, whenever they try to log in, it always says the login is invalid and that the username or password is not correct. I've tried a million times, making sure everything is spelled properly, and even created a new user, and still nothing. Any ideas? I am unable to test it on a Windows client, so I don't know if it's purely a Mac issue.
