LDAP auth generates a lot of empty requests, but none authentication request

It seems the ejabberd guide in SVN is up to date with the SVN source code, right?

I have solved this by using lates SVN snapshot. Also it seems the things are mostly solved in devel version (at least to my observation). So if you would want to give it a try, I attach my ebuild, which does build ejabberd on gentoo from SVN. Its basically the copy of the latest tar based ebuild, so nothing much spectacular ;-). Also beware it does not use sasl in run script.
