Writing access denied to /tmp/tao

When a user creates a tao server, the directory /tmp/tao is by default owned by this user. If another user tries to create a server, the write access to /tmp/tao is denied and the server creation fails.

Default access to /tmp/tao when created by user camille : drwxr-xr-x 2 camille users 4096 mai 26 15:32 tao/

Workaround : Execute chmod -R a+w /tmp/tao
