New issue 348: InvalidRequestError when connecting with LDAP
https://bitbucket.org/conservancy/kallithea/issues/348/invalidrequesterror-when-connecting-with

Samuel Delisle:

After upgrading from 0.3.3 to 0.4.1, I get an InvalidRequestError when trying to login. The error output is this:

‌

```
InvalidRequestError: This Session's transaction has been rolled back due to a previous
exception during flush. To begin a new transaction with this Session, first issue
Session.roll). Original exception was: (raised as a result of Query-invoked autoflush;
consider using a session.no_autoflush block if this flush is occurring prematurely)
(sqlite3.ProgrammingError) You must not use 8-bit bytestrings unless you use a text_factory
that can interpret 8-bit bytestrings (like text_factory = str). It is highly recommended
that you instead just switc your application to Unicode strings.
[SQL: u'UPDATE users SET password=?, extern_name=? WHERE users.user_id = ?']
[parameters: ('*************', 'CN=*******,OU=D\xc3\xa9veloppement,OU=*********,
DC=*****,DC=*****', 3)] (Background on this error at: http://sqlalche.me/e/f405)
```

The error seems to be caused by the non-ascii character in the first OU, which should be “Développement”. Login works fine with another user that is not part of that particular group.

I guess a workaround would be to have IT change the name of that group \(and possibly several others\), but they probably won’t like me…
