When using Access Connections with a saved password and Client Security Solution is installed or uninstalled, the saved password profiles may now fail to connect (fail authentication).
This could occur on ThinkPads using Access Connections and Cliente Security Solution. Access Connections will use Client Security Solution (CSS), if present, to encrypt/decrypt saved passwords. If CSS is uninstalled, Access Connections can no longer decrypt the saved password and authentication will fail. Also, if CSS is installed after a password has already been saved in Access Connections without CSS present, then authentication will fail since CSS cannot decrypt the native Windows encryption.
You can just edit the Access Connections profile and re-enter the saved password to resolve.
