I need to customize Plone login form without make changes in plone original login-form https://github.com/plone/Products.CMFPlone/blob/master/Products/CMFPlone/skins/plone_login/login_form.cpt i think there are two ways one way is to use override.zcml to change login-form and a simple login.pt file :
<browser:page
for="OFS.interfaces.IApplication"
name="plone-root-login"
class="Products.CMFPlone.browser.admin.RootLoginRedirect"
permission="cmf.ManagePortal"
template="templates/login.pt"
/>
Traceback:
File "/Plone/buildout-cache/eggs/Products.CMFPlone-4.3.3-py2.7.egg/Products/CMFPlone/browser/admin.zcml", line 43.2-48.8
<browser:page
for="OFS.interfaces.IApplication"
name="plone-root-login"
class=".admin.RootLoginRedirect"
permission="cmf.ManagePortal"
/>
File "/Plone/buildout-cache/eggs/my_app/my/app/browser/overrides.zcml", line 7.4-12.10
<browser:page
for="OFS.interfaces.IApplication"
name="plone-root-login"
class=".admin.RootLoginRedirect"
permission="cmf.ManagePortal"
/>
And Second one to set external_login_url in default/propertiesTool.xml i tried but changes not reflected.So what to do please tell me ???
