Merge lp://qastaging/~dreis-pt/ocb-addons/7.0-bug1079476-dr into lp://qastaging/ocb-addons

I need to add that I'm using this fix in production.

Hi Daniel, thanks for looking into this!

What I read on the Internet about python-ldap and unicode confirms what Olivier Dony writes on the bug report [1]. Any input that is passed on to python-ldap should be encoded as utf-8 instead of the default Python unicode. I can confirm this simply by logging on using a user name with a unicode character. This gives basically the same error as the one from the bug report. I think it would be much appreciated if you completed the mission to cover all strings passed to the LDAP server.

Code nit in l.18: given that the 'conf' dictionary comes from a raw sql query, it could be that conf['ldap_password'] is None. The following is probably safer in that case

    (conf['ldap_password'] or '').encode("utf-8")

Setting to work-in-progress after 5 weeks of no response. Can you backport your fix to openobject-addons when you are happy with it?

Yes, I'll get back to it as soon as I can; just been too busy lately.
