We have a few Macs in our organization we want to add to our domain and enable users to login with their network credentials. On one Mac running Mavericks we successfully added it to the domain and can login with any network account. We have tried on two other Macs running Yosemite and are able to add them to the domain, but can only login with one network account. The other network accounts either don't accept the username/password (even though it worked on Mavericks' Mac) or it asks the user to immediately change their password, even though their password was recently changed per policy. I'm thinking this is an issue with Yosemite since Mavericks isn't giving us this issue. Is there some way to enable any network user to login to the Macs running Yosemite? We set the network login to allow anyone, so it's not being blocked that way. Any thoughts are appreciated.
