- $configref->{"name_regex"} = "^[a-z][-a-z0-9_]*\$";
- $configref->{"name_regex_system"} = "^[A-Za-z][-A-Za-z0-9_]*\$";
+ $configref->{"name_regex"} = "^[a-z][-a-z0-9_.]*\$";
+ $configref->{"name_regex_system"} = "^[A-Za-z][-A-Za-z0-9_.]*\$";
That's a regex, so a bare . is almost certainly not what you want there.
Why does users-admin use adduser instead of useradd? It's not that
it shouldn't, but adduser is primarily designed as a policy compliant
method for maintainers to interface in a policy compliant way with user
management in maintainer scripts - extending it to be a general purpose
user management script for all manner of environments isn't what it's
aimed at, and I'm not convinced it will be a good thing to make it
general purpose. I think before changing the naming policy of adduser,
it does make sense to stop for a moment and check if you're using the
right tool for the job.
Cheers,
