Exception with ldap signin when the password includes accented characters

When the password of the user contains an accented character like "à" or "ç" for instance, the following exception is raised :

I will redo LDAP to use django-auth-ldap, looking at it now.

Actually, looks like we'll still need to hack around, because that app works differently - I will borrow some code from django-auth-ldap though.

Samuel, can you try using password.encode('utf-8') inside the "simple_bind_s" call in the end of askbot/deps/django_authopenid/util.py ? Does that help?

Evgeny (13 years ago)

I have already tried to encode the password in utf-8 but it changes nothing.

Samuel (13 years ago)

Could you explain briefly the difficulties to integrate django-auth-ldap? In my opinion the main reasons to use it are : - bind with a robot, then verification of the user's credentials by queries. This method is the right one. I have done ugly patches in askbot to make the simple bind working with an active directory using multiple domains. I can give further details if you want. - fill last name, first name, email and others fields automatically - set automatically permissions - limit the connection to certain ldap groups
