Typeerror not all arguments converted during string formatting

[dennis.liou@…]

I find that the error happened in a line bind_name = (self.bind_dn%user).encode('utf8') in ldapauth/store.py:26. Please tell me why, and how to solve it.

[Ryan J Ollos]

What value have you configured in trac.ini for [ldap] bind_dn?

Which version of Trac are you running? If you are running 1.0 or later, you should install from the 1.0 branch​ rather than the 0.11 branch​.

I running with trac 1.0.2. Is there bind_user same with bind_dn? Or the two setting should be set simultaneously.
