Please do not send attachments to this list (they can make it
more difficult to read/cite them). Put the error information
directly in the main message mody (rather than a message attachment).

This "[...]" around the user is strange.

The "createToken" code:

def createToken(extra=''):
    manager = getUtility(IKeyManager)
    secret = manager.secret()
    user = _getUserName()
61: return hmac.new(secret, user + extra, sha).hexdigest()

This looks as if "user" were a list while it should be a string.


The error is likely somewhere in "plone.app.ldap". Likely, it passes the
wrong data type as user name.

You may try a different version of "plone.app.ldap" (maybe, you
accidentally got a buggy one). Or contact the authors of
"plone.app.ldap" to learn what they propose to get the problem fixed.

If nothing else helps, debugging the authentication process will
at least reveal which component is responsible and like what to
do about it.
