[Samba] win2k usernames with spaces

[maq]

Hi all,
	one of the win2k clients of my network uses an ID with
one space inside, e.g. "jack smith". I succeeded in creating a
Linux user with such a name, but have troubles in adding him to 
the smb users. 
Any suggestion?

PS Running RH 8.0 & Samba 2.2.5 When i had RH 6.2 & Samba ?.?.? the
trick worked out.

Thanx

maq
