What to do?

You shouldn't use sudo for graphical applications, such as gedit. Use gksudo instead.

What's causing the error

I'm not sure. Apparently, the reason of error you get is that gedit is trying to invoke SessionManager's Inhibit method via D-bus.

If normal applications can connect to dbus, they should have some config files in /usr/share/dbus-1. I expected them to be /usr/share/dbus-1/services/org.gnome.SessionManager.service or /usr/share/dbus-1/system-services/org.gnome.SessionManager.service. On my Debian machine I can't find any of them.

So, my guess is gnome-session doesn't need a dbus .session file as it's not a normal application. In fact, it is itself responsible for starting the per-session instance of dbus. But the per-session instance of dbus is in fact per-user per-session, so it can't interact with graphical application running under different user than you (and root user, running sudo gedit, is different than you).

Solution

The solution is not to used both the options default_permissions and allow_other (which I didn't try in my original experiments).

Explanation

The problem seems to be quite simple. When you give the option default_permissions in fusermount then fuse's permission control of the fuse mount is handled by the kernel and not by fuse. This means that the REMOTE_USER's uid/gid aren't mapped to the LOCAL_USER (sshfs.c IDMAP_NONE). It works the same way as a simple nfs fs without mapping.

So, it makes sense to prohibit the access, if the uid/gid numbers don't match.

If you have the option allow_other then this dir is writable only by the local user with uid 699, if it exists.

From fuse's man:

'default_permissions'

   By default FUSE doesn't check file access permissions, the
   filesystem is free to implement its access policy or leave it to
   the underlying file access mechanism (e.g. in case of network
   filesystems).  This option enables permission checking, restricting
   access based on file mode.  It is usually useful together with the
   'allow_other' mount option.

'allow_other'

   This option overrides the security measure restricting file access
   to the user mounting the filesystem.  This option is by default only
   allowed to root, but this restriction can be removed with a
   (userspace) configuration option.

Bash – Locating PHP extension folder using bash

Maybe you should do this:

php-config --extension-dir

If php-config doesn't exist, then apt-get install php-config if Ubuntu/Debian or yum install php-config if CentOS/Red Hat)

That command will give exact location of your php extension folder.

Don't forget to change your php.ini in order to use extensions.
