User-Agent: Mozilla/4.5 [en] (WinNT; U)

Description of problem:
The only available shadow-utils rpm for Red Hat 9.0 is shadow-utils-4.0.3-6. It seems that this rpm ignores users whose 
usernames are in upper case.
ie:
The following releases:
7.2 = shadow-utils-20000902-9.7
7.3 = shadow-utils-20000902-9.7
8.0 = shadow-utils-20000902-12.8

have the following code in the file libmisc/chkname.c

good_name(const char *name)
{
        /*
         * User/group names must start with a letter, and may not
         * contain colons, commas, newlines (used in passwd/group
         * files...) or any non-printable characters.
         */
        if (!*name || !isalpha(*name))
                return 0;

While the shadow-utils-4.0.3-6 has

good_name(const char *name)
{
        /*
         * User/group names must match [a-z_][a-z0-9_-]*
         */
        if (!*name || !((*name >= 'a' && *name <= 'z') || *name == '_'))
                return 0;

Thus this rpm ignores characters from A-Z. This issue is casing problem in utilities such as useradd

Version-Release number of selected component (if applicable):
