It's been brought to my attention that there might be desires to use
spaces and $s in login names[*], and I wonder if there's a really good
reason (besides the obvious ones :-) to not allow all but ':' in login
names? (If admins want it, give 'em the rope etc.)

The following patch works at least on 1.5.3_ALPHA, and I'd like to commit
it if there are no major objections:

[*] e.g. when setting up samba as PDC you need login names that are like
    " machine$ " - note the spaces.
