This is an issue we've been seeing since Catalina. Scenario: MacBook running 10.15.x, bound to AD, using mobile accounts, SMB network home. New user gets provisioned by authenticating against AD over an ethernet connection. Once in newly-created user account, wireless is configured and password stored in Keychain. During subsequent logins without an ethernet connection, the following error appears almost immediately:
However, the network home globe appears in the Dock, but when attempting to open it, the following message appears:
So it is able to access the network home, but also prompts for a password every time, despite credentials being stored in the Keychain.
Up until Mojave, this was working flawlessly for us. It seems like this is a timing issue, where the system is attempting to mount the network home prior to the wireless connection being fully established.
Any thoughts?
