Description of problem:
Able to create users such as Bob, Larry and Tom with a capital first letter
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install F13-Alpha
2. Upon First Boot choose a username with leading Capital
3. It will be accepted.
Leading capitals and I believe any capitals in usernames should be rejected per long standing linux standards
Thank you for the bug report. Neither of the text-mode or graphical user/group management tools restrict user accounts to all lowercase.
# useradd -p '' Guest
# getent passwd Guest
In additional, the documentation  places no restrictions on case sensitivity for user account names.
Thanks for the information James. I'm marking this closed not a bug if that is the intended and allowable behavior. Several in #fedora felt that Ucase First Letter should not be allowed. Thus the reason I reported it.
