In 'Users and Computers' section I'm adding user with nonstandard latin letters in name, Piotr Wiśniewski for example. Login of that user is pwisniewski. When I'm trying to configure Outlook 2010 to use that account samba gets an error:
[2014/03/20 11:08:19.401931, 3] ../lib/util/charset/convert_string.c:316(convert_string_handle)
convert_string_internal: Conversion error: Illegal multibyte sequence(Piotr Wiśniewski)

When I create account without national letters in name Outlook connects correctly to Zentyal server.
