[Samba] URGENT: big problem with displayName.

[Stéphane PURNELLE]

dbcheck detect the problem : 

/usr/local/samba/bin/samba-tool dbcheck
Checking 1229 objects
convert_string_talloc: Conversion error: Illegal multibyte sequence(�ois 
Laschet)

attrname, [val])

    return dsdb._dsdb_normalise_attributes(ldb, ldap_display_name, 
ldif_elements)


unix charset was ISO-8859-15

For permit user to work, we created new user.
Now, how to clean theses bad users ?

thx
