Redmine

I'm writting plugin, that make periodicaly user's synchronisation from LDAP

When I run rake task I see the error "rake aborted! \x82" from ASCII-8BIT to UTF-8"
The command, that I run is "rake redmine:make_ldap_full_sync"

I know, that this error in net-ldap library, but it work outside rake

error cause this code

ldap_connection.search(:base => auth_source.base_dn, :filter => filter, :return_result=>0)

Any help

There is my rake task full code
