Greald this is what I had done (note the if statement also has similar
hack)
static int
good_name(const char *name)
{
/*
* User/group names must match [a-z_][a-z0-9_-]*
*/
if (!*name || !((*name >= 'a' && *name <= 'z') || *name == '_'
|| *name == '.'))
return 0;
while (*++name) {
if (!((*name >= 'a' && *name <= 'z') ||
(*name >= '0' && *name <= '9') ||
*name == '_' || *name == '-' || *name == '.' ||
(*name == '$' && *(name+1) == NULL)))
return 0;
}
return 1;
}
After compiling and installing, useradd now accepts usernames with a dot
but the redhat graphical user manager doesn't. I guess redhat
implemented their own check.
