I've got a Cisco IPSEC VPN connection in my network settings on a Yosemite machine. It works fine, aside from prompting for a password on every single connection. The saved password is ignored entirely.
If I enter the password under the network settings and click connect, the saved password vanishes, and the dialog prompting for a password appears. I've verified that the password is correct (it's copy-pasted from a document).
Things that didn't work
A suggested solution to this for Snow Leopard was to save the password, open Keychain Access, locate the "Xauth" key in the system keychain, and grant
/usr/libexec/configdaccess to the key. This had no effect.
Usual permissions repair/disk check stuff
If I watch keychain access while hitting the connect button, the saved password vanishes outright from the keychain right when the dialog appears.
How do I get the password correctly saved so I don't have to rekey it on every connection?
