samba - Sep 2014 - Creating users with non-ascii chars fails

Hi list!

I'm trying to create a user with non-ascii characters in the name, but this
fails:

root at test-samba4:~# samba-tool user create foa --given-name='foa?'
New Password:
Retype Password:
ldb_handler_fold: unable to casefold string [foa?]
ldb_handler_fold: unable to casefold string [foa?]
ldb_handler_fold: unable to casefold string [foa?]
ldb_handler_fold: unable to casefold string [foa?]
Conversion error: Illegal multibyte sequence(?)
ERROR(ldb): Failed to add user 'foa':  - objectclass_attrs: attribute
'displayName' on entry 'CN=foa?,CN=Users,DC=s4,DC=local'
contains at least one invalid value!

My locale is set to en_US.UTF-8, the "unix charset" samba variable is
set to
"UTF-8".

This is samba 4.1.11, on a Slackware64 13.1 system, built with --with-iconv.
I have the iconv header files (they came with my glibc) but I do not have
libiconv.

I can create users in the ADUC with non-ascii characters without problems.

Can anyone give me a hint about where to look to solve this?

Thanks a lot!

Roel


Some extra info:

./configure says the following about iconv:

Checking for header iconv.h : yes
Checking for library iconv  : no
Checking for library iconv  : not found
Checking for iconv_open     : ok

root at test-samba4:~# env | grep -E 'LC|LANG'
LC_ALL=en_US.UTF-8
LC_COLLATE=C
LANG=en_US.UTF-8

root at test-samba4:~# testparm -sv | grep charset
        ...
        dos charset = CP850
        unix charset = UTF-8

root at test-samba4:~# iconv -V
iconv (GNU libc) 2.11.1

1.) It's a bad idea to create users with special characters. You will
get trouble with other connected applications somewhen for sure. :-)


2.) It's not a bug (done on RHEL7):
    # samba-tool user create foa --given-name='foa?'
    New Password:
    Retype Password:
    User 'foa' created successfully


3.) Can you check
    # smbd -b | grep icon -i
       HAVE_ICONV_H
       HAVE_ICONV
       HAVE_ICONV_OPEN
       HAVE_NATIVE_ICONV
    This is the output on my RHEL7
