Yes... I completely agree. My tiny fix got us over a problem here. Maybe it
can be fixed a bit better and still handle the situation I need handled.

We are semi-automatically adding users into the passwd, smbpasswd, and valid
users lists based on input from a number of sources, depending on the scenario.
We are supporting server-based login, PDC login, NDS, etc. We are moving
towards an LDAP solution... but...
Users may come in with spaces already in their user names from their
previously selected usernames in NT-land or otherwise and we don't want and
can't really automatically reassign their usernames to some other more
samba-valid user name (using a user list) because of possible name collision.
Is there any problem in working to make user_in_list into the 'more robust'
version that will handle all the current delimiters and _also_ take quoted
names with spaces in the middle of them? This would take care of the problem I
noted earlier where, if you get rid of the space as a delimiter, you need to be
very careful NOT to put extra spaces in the user list. (I can see that as
causing problems all the time!)
