Access control and "odd" user names

["Hoff, Lawrence" <hoff@bnl.gov>]

	Looking at the YACC code for parsing access control files, I see
that "name lists" consist of comma separated "names":

uag_user_list:	uag_user_list ',' uag_user_list_name
	|	uag_user_list_name
	;

uag_user_list_name:	tokenNAME

	Looking at the LEX code, I see that names consist of the
following characters:

name	[a-zA-Z0-9_\-:\.\[\]<>;]+




	That works fine for the user name I was assigned on my LINUX
box, but it does not work well for the user name I was assigned on
my Windows box, which has an embedded space (' ').

	The expedient solution is to change the space to another
semi-invisible character on my Windows box. However, I was wondering
whether others have run into this, and/or perceive this as an issue
worth trying to address, or whether there are additional problem
associated with supporting a space character in access control.

P.S. I *suspect* that there are no issues with supporting embedded
spaces in user names (other than readability issues), since the user
name string is treated as a string once it has been read in, and that
it is no less readable than other strings with embedded spaces, such
as scan rates of "1 second".
