LDAP users cannot change password

[EvaSDK]

Support for this is not implemented and I doubt it would be any useful anyway so it would be best to just hide this menu entry from LDAP users.

This is made a bit difficult though because there is currently no bit of information in the model that allows us to known whether the model maps an external authentication backend or refers to a purely database bound user.

Pyshop can use LDAP?
I configure LDAP reported the following error,
I do not know why
ERROR [/root/pyshop/local/lib/python2.7/site-packages/pyshop/models.pyc][waitress] ERROR while using LDAP connection

@tom-piao You must install the pyshop[ldap] package the same way you installed the pyshop[waitress] package, or allow the virtualenv access to global packages with python-ldap installed.
