Could anyone of you please help me to implement LDAP authentication using Django. I want to develop a web application which should allow users to access the application post LDAP authentication. I have coded the basic things but I get some failures.

I get below error when i run my project
exception

Could anyone of you please help me here.

My use case:
user should be able to land on some home page after a successful login or should land back on same login page if provided credentials are invalid.

The error indicates that you are passing a single Python path where you should actually pass a list of Python paths, i.e. django.some.module.path instead of ['django.some.module.path']

Django then iterates over the string, and tries to import each character. In case of django.some.module.path, Django tries to import d, which gives you the error you are seeing.

To pinpoint the exact source of the error, you have to provide the complete traceback. You can click on 'Switch to copy-and-paste view' on the Debug Error page.

Update:

Here is your error:

AUTHENTICATION_BACKENDS = ('django_auth_ldap.backend.LDAPBackend')

Single entry tuples need a comma, like this:

AUTHENTICATION_BACKENDS = ('django_auth_ldap.backend.LDAPBackend',)
