Dash in reseller username invalid

[johannes]

I just tried to add a new reseller, with a dash in the username (abc-xyz), and get "invalid username", cannot create it. Without dash (abcxyz) no prob.

Are dashs genereally not allowed, or how to circumvent this?

Thx

Hyphens are valid for linux usernames at least, so my best guess would be that DA enforces stricter requirements to be compatible with perhaps older linux distros, or bsd? This is the default regex in Debian 12: ^[a-z][-a-z0-9_]*$ (from man adduser.conf).
