This is more of a general OS X question.
I recently had to upgrade a bot mini from 10.8 and to 10.12.
In 10.8 when you connect to a server and you have the password saved in the keychain, the server simply mounts with no authentication prompt. Im finding in 10.12 that even though you have the password saved in the keychain, you still get the authentication prompt. The password IS filled in for you, but you are required to click ok.
This is problematic for me. I have a launch agent setup to call an applescript that does various things. The first thing it does is check if a particular server is mounted, and if not it mounts it. It is now getting stuck at the authentication prompt.
Is what I am experiencing expected behavior? Is there a way to get the mounting of a network volume to work as it did before without the authentication prompt?
