If no group was specified, but a group by the same name as the user exists, an error was raised in the situation where USERGROUPS_ENAB is enabled in /etc/login.defs (which is the case for almost every major linux distro). In this case, the user will be put in group 100 (which is usually the "users" group on those same distros). This is currently only done in the base class, as the issue may not exist on other platforms like AIX or the BSDs. Fixes #6210
