[Samba] usernames with spaces

Title: Message

Hello,   I am moving from a NT environment to a RH one.  My main problem is the user home directories.   The users and homedir are create with a space in them: '<first> <lastname>'    I have to create 'John Doe' shares with 'John Doe' as the user. When a user try to connect to his homeshare, he is prompted for the user/password pair and his unable to use them.   Did someone solved this ?   Many thanks, Guy
