BUT, the I think that the real reason that dots should not be allowed in user names is because this doesn't allow dots:
RFC 4282 - The Network Access Identifier
There is no requirement to follow this for usernames; however, I think we should.
Unless I'm misreading the RFC, it does allow dots in usernames?
nai = username nai =/ "@" realm nai =/ username "@" realm
username = dot-string dot-string = string dot-string =/ dot-string "." string
I don't know myself but Fedora Core 4 allows dots in usernames. useradd asdf.adsf under Fedora Core 4 works just fine as well as userdel asdf.asdf . I wonder which direction RHEL will follow in the future since Fedora is usually the test ground for newer stuff in RHEL.
It seems it's really a bug in RHEL 3, RHEL 2.1 allows a dot, so does RHEL 4.x (and IMHO a dot should be allowed, I don't care if a package from the previous millennium doesn't work anymore)
I wonder if I could just install shadow-utils from RHEL4 on my CentOS 3.x boxes (maybe it will work after rebuilding the RPM)
